2013-05-03mainboard/{asus/f2a85-m,amd/thatcher}: move UDELAY_LAPICDavid Hubbard
Stefan Reinauer suggested 'select UDELAY_LAPIC' did not belong in f2a85-m/Kconfig. It got there via copy-paste from thatcher/Kconfig so this commit removes the 'select UDELAY_LAPIC' from both and puts it in cpu/amd/agesa/family15tn/Kconfig Since f2a85-m is the only Thatcher board coreboot supports right now, this should not break any other boards.

2013-05-01armv7: invalidate TLB entries as they are added/modifiedDavid Hendricks
The old approach was to invalidate the entire TLB every time we set up a table entry. This worked because we didn't turn the MMU on until after we had set everything up. This patch uses the TLBIMVAA wrapper to invalidate each entry as it's added/modified.

2013-05-01AMD Hudson A55E: Remove GEC firmware blob kconfig promptBruce Griffith
The "gigabit ethernet controller" (GEC) block was added to AMD Hudson A55E to integrate ethernet capabilities into an AMD southbridge. The GEC is designed to work with B50610 and B50610M gigabit PHY chips from Broadcom. These parts may not be generally available in small quantities for embedded development. The GEC block requires an opaque firmware blob to function. The GEC blob is controlled by AMD and Broadcom and is not available from coreboot.org. This change removes GEC support from AMD Parmer and AMD Thatcher mainboards since these boards do not have the Broadcom PHY. AMD has requested that the GEC be hidden for Hudson FCH since the PHY parts are not generally available. This Kconfig option can make it appear that this is a viable and supported way to add Ethernet to an embedded board. It is possible to use the Hudson GEC block with other PHYs, but this requires development of a custom GEC blob and a custom Ethernet driver. A custom GEC blob has been developed for a Micrel PHY, but there is no accompanying driver.

When TIMER_QUEUE is configured on call the timer callbacks on entry into a state but before its entry callbacks. In addition provide a barrier to the following states so that timers are drained before proceeding. This allows for blocking state traversal for key components of boot. BS_OS_RESUME BS_WRITE_TABLES BS_PAYLOAD_LOAD BS_PAYLOAD_BOOT Future functionality consists of evaluating the timer callbacks within the device tree. One example is dev_initialize() as that seems state seems to take 90% of the boot time. The timer callbacks could then be ran in a more granular manner.

2013-04-30Google/Snow: Temporary fix for resume failure.Hung-Te Lin
The DDR3 memory initialization (with "mem_reset" set on normal boot) will cause resume to be unstable, especially when X is running. System may show X screen for few seconds, then crash randomly and unable to recover - although text console may still work for a while. Probably caused by corrupted memory pages. 'mem_reset' (which refers to RESET# in DDR3 spec) should be enabled according to DDR3 spec. But it seems that on Exynos 5, memory can be initialized without setting mem_reset for both normal boot and resume - at least no known failure cases are found yet. So this can be a temporary workaround. Verified by booting a Google/Snow device with X Window and ChromeOS, entering browser session with fancy web pages, closing LID to suspend for 5 seconds, then re-opening to resume. Suspend/resume worked as expected. Also tried the "suspend_stress_test" with X running and finished 100 iterations of suspend/resume test without failure.

2013-04-23Intel microcode: Return when `microcode_updates` is `NULL`Vladimir Serbinenko
Add a safety check in function `intel_update_microcode` to return when accidentally `NULL` is passed as `microcode_updates`, which would lead to a null pointer dereference later on. for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) { While at it, use `return NULL` for clarity in function `intel_microcode_find` and include the header file `stddef.h`. for it. The review of this patch had some more discussion on adding more comments and more detailed error messages. But this should be done in a separate patch. For clarity here some history, on how this was found and what caused the discussion and confusion. Originally when Vladimir made this improvement, selecting `CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob `cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference later on causing a crash. for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) { Vladimir fixed this by returning if `microcode_updates` is `NULL`, that means no file is found and successfully tested this on his Lenovo X201. When pushing the patch to Gerrit for review, the code was rewritten though by Aaron in commit »intel microcode: split up microcode loading stages« (98ffb426) [1], which also returns when no file is found. So the other parts of the code were checked and the safety check as described above is added.

2013-04-23exynos5250: ungate the product ID registerDavid Hendricks
This makes sure that the product ID (PRO_ID) register can be read when the OS kernel is figuring out what kind of CPU it's running on. For historical reference, the original U-Boot code seems to have worked basically by accident here. The hardware has a quirk where by reading the value before gating the IP block keeps the value persistent. U-Boot reads the chip ID early on to distinguish between chip family, but we do not mix code the same way so we do not read the chip ID. Since the value has been read before the clock gating happens, the value remains available for the kernel to use during the decompression stage. We don't want to rely on that behavior when using coreboot. Instead the kernel should gate unused IPs.

Therefore use `#include <sb_cimx>` everywhere, which is what some AMD SB800 based boards already do. The only effect is, that the compiler will not needlessly look into directories which do not contain the header file [1]. The following command was used for the replacement. $ git grep -l sb_cimx.h src/mainboard/ | xargs sed -i 's/#include "sb_cimx.h"/#include <sb_cimx.h>/' [1] http://gcc.gnu.org/onlinedocs/cpp/Search-Path.html Change-Id: I96ab34bac1524e6c38c85dfe9d99cb6ef55e6d7c Signed-off-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-on: http://review.coreboot.org/3118 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2013-04-17armv7/exynos5250: Deprecate sdelay in favor of udelayDavid Hendricks
This gets rid of the clock-tick based sdelay in favor of udelay(). udelay() is more consistent and easier to work with, and this allows us to carry one less variation of timers (and headers and sources...). Every 1 unit in the sdelay() argument was assumed to cause a delay of 2 clock ticks (@1.7GHz). So the conversion factor is roughly: sdelay(N) = udelay(((N * 2) / 1.7 * 10^9) * 10^6) = udelay((N * 2) / (1.7 * 10^3)) The sdelay() periods used were: sdelay(100) --> udelay(1) sdelay(0x10000) --> udelay(78) (rounded up to udelay(100)) There was one instance of sdelay(10000), which looked like sort of a typo since sdelay(0x10000) was used elsewhere. sdelay(10000) should approximate to about 12us, so we'll stick with that for now and leave a note.

Add a microsecond timer, its declaration, the function to start it, and its usage. To start it, one calls timer_start(). From that point on, one can call timer_us() to find microseconds since the timer was started. We show its use in the bootblock. You want it started very early. Finally, the delay.h change having been (ironically) delayed, we create time.h and have it hold one declaration, for the timer_us() and timer_start() prototype. We feel that these two functions should become the hardware specific functions, allowing us to finally move udelay() into src/lib where it belongs.

2013-04-11Persimmon/Fam14/SB800 DSDT: Split into common areasMike Loptien
Split the Persimmon DSDT into common code areas. For example, split the Southbridge specific code into the Southbridge directory and CPU specific code into the CPU directory. Also adding the superio.asl file to the Persimmon DSDT tree. This file is empty for the moment but will be necessary in the future. I have also emptied the thermal.asl file in the mainboard directory because it does not seem to perform as intended (fan control does not change when it is brought back into the code base) and it has been inside a '#if 0' statement for a long time. Removing it until it is decided that it is actually necessary. This change was verified in three different ways: 1. Visual comparison of the compiled DSDT pulled from the Persimmon after booting into Linux using the ACPI tools acpidump, acpixtract, and iasl. The comparison was done between the DSDT before and after doing the split work. This test is somewhat difficult considering the expanse of the changes. Blocks of code have been moved, and others changed. 2. Linux logs were dumped before and after the DSDT split. Logs dumped and compared include dmesg and lspci -tv. Neither log changed significantly between the two compare points. 3. The test suite FWTS was run on the Coreboot build both before and after doing the DSDT split with the command 'sudo fwts -b -P -u'. The flag -b specifies all batch jobs, -P specifies all power tests, and -u specifies utilities. Interactive jobs were not run as most of them consist of laptop checks. Again, there were no significant changes between the two endpoints. These tests lead me to believe that there was no change in the functionality of the ACPI tables apart from what is known and expected. This patch is the first of a series of patches to split the DSDT. The ASRock patch was merged before this one and breaks the ASROCK E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/). Please be aware of this dependency when pulling these patches. Other patches that depend on this patch are 'AMD Fam14: Split out the AMD Fam14 DSDT' (http://review.coreboot.org/#/c/3051/) and 'Fam14 DSDT: Also return for unrecognized UUID in _OSC' (http://review.coreboot.org/#/c/3052/) Change-Id: I53ff59909cceb30a08e8eab3d59b30b97c802726 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/3048 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

It seems like a good idea to do this early to ensure that the input gate capacitance has had a chance to charge, and if we decide to use actually use that information during the ROM stage to do earlier RW firmware selection. It is not guarded by a ChromeOS config variable because those lines are always intended to be input GPIOs, regardless of whether we're running ChromeOS or not.

2013-04-10armv7: replace read/write macros with inlinesDavid Hendricks
This enables type checking for safety as to help prevent errors like http://review.coreboot.org/#/c/3038/ . Now compilation fails if the wrong type is passed into readb/readw/readl/writeb/writew/writel or other macros in io.h. This also deprecates readw/writew. The previous definition was 16-bits which is incorrect since wordsize on ARMv7 is 32-bits and there was only 1 instance of writew (#if 0'd anyway). Going forward we should always use read{8,16,32} and write{8,16,32} where N specifies the exact length rather than relying on ambiguous definition of wordsize. Since many macros relied on __raw_*, which were basically the same (minus data memory barrier instructions), this patch also gets rid of __raw_*. There were parts of the code which ended up using these macros consecutively, for example: setbits_le32(&regs->ch_cfg, SPI_CH_RST); clrbits_le32(&regs->ch_cfg, SPI_CH_RST); In such cases the safe versions of readl() and writel() should be used anyway. Note: This also fixes two dubious casts as to avoid breaking compilation.

This re-factors the Exynos5 I2C code to be simpler and use the new API, and updates users accordingly. - i2c_read() and i2c_write() functions updated to take bus number as an argument. - Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and i2c_write(). If a chip needs special handling we should take care of it elsewhere, not in every low-level i2c driver. - All the confusing bus config functions eliminated. No more i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this is handled automatically when the caller does a transaction and specifies the desired bus number. - i2c_probe() eliminated. We're not a command-line utility. - Let the compiler place static variables automatically. We don't need any of this fancy manual data placement. - Remove dead code while we're at it. This stuff was ported early on and much of it was left commented out in case we needed it. Some also includes nested macros which caused gcc to complain. - Clean up #includes (no more common.h, woohoo!), replace debug() with printk().

2013-04-09replace device/i2c.h with simpler versionDavid Hendricks
The existing header was imported along with the Exynos code and left mostly unchanged. This is the first patch in a series intended to replace the imported u-boot I2C API with a much simpler and cleaner interface: - We only need to expose i2c_read() and i2c_write() in our public API. Everything else is board/chip-dependent and should remain hidden away. - i2c_read and i2c_write functions will take bus number as an arg and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to error and end up cluttering the code since the user needs to save the old bus number, set the new one, do the read/write, and restore the old value (3 added steps to do a simple transaction). - Stop setting default values for board-specific things like SPD and RTC bus numbers (as if we always have an SPD or RTC on I2C). - Death to all the trivial inline wrappers. And in case there was any doubt, we really don't care about the MPC8xx. Though if we did then we would not pollute the public API with its idiosyncrasies.
