2015-07-03SeaBIOS: Change clean to just 'rm -rf seabios/out'Martin Roth
When running 'make clean' if the seabios directory is present, we get warnings about not having IASL installed or that the C compiler can't be executed. It fails to actually run the clean because we're not correctly passing in the toolchain. Just do what the SeaBIOS clean does directly and delete the 'out' directory without actually calling the SeaBIOS clean. Here were the previous warnings: % make clean Unable to execute the C compiler (). Please install a working compiler and retry. Makefile:104: *** "Please upgrade the build environment".

2015-06-05lib: Unify log2() and related functionsJulius Werner
This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

2015-06-03libpayload: usb: Support MTK xHCI host controllerYidi Lin
1. There is a mis-understanding to calculate the value of TD Size in Normal TRB. For MTK's xHCI controller it defines a number of packets that remain to be transferred for a TD after processing all Max packets in all previous TRBs, that means don't include the current TRB's. 2. To minimize the scheduling effort for synchronous endpoints in xHC, the MTK architecture defines some extra SW scheduling parameters for HW. According to these parameters provided by SW, the xHC can easily decide whether a synchronous endpoint should be scheduled in a specific uFrame. The extra SW scheduling parameters are put into reserved DWs in Slot and Endpoint Context. But in coreboot synchronous transfer can be ignored, so only two fields are set to a default value 1 to support bulk and interrupt transfers, and others are set to zero. 3. For control transfer, it is better to read back doorbell register or add a memory barrier after ringing the doorbell to flush posted write. Otherwise the first command will be aborted on MTK's xHCI controller. 4. Before send commands to a port, the Port Power in PORTSC register should be set to 1 on MTK's xHCI so a hook function of enable_port in generic_hub_ops_t struct is provided.

2015-06-02arm64: Decouple MMU functions from memrangesJulius Werner
The current arm64 MMU interface is difficult to use in pre-RAM environments. It is based on the memranges API which makes use of malloc(), and early stages usually don't have a heap. It is also built as a one-shot interface that requires all memory ranges to be laid out beforehand, which is a problem when existing areas need to change (e.g. after initializing DRAM). The long-term goal of this patch is to completely switch to a configure-as-you-go interface based on the mmu_config_range() function, similar to what ARM32 does. As a first step this feature is added side-by-side to the existing interface so that existing SoC implementations continue to work and can be slowly ported over one by one. Like the ARM32 version it does not garbage collect page tables that become unused, so repeated mapping at different granularities will exhaust the available table space (this is presumed to be a reasonable limitation for a firmware environment and keeps the code much simpler). Also do some cleanup, align comments between coreboot and libpayload for easier diffing, and change all error cases to assert()s. Right now the code just propagates error codes up the stack until it eventually reaches a function that doesn't check them anymore. MMU configuration errors (essentially just misaligned requests and running out of table space) should always be compile-time programming errors, so failing hard and fast seems like the best way to deal with them. BRANCH=None BUG=None TEST=Compile-tested rush_ryu. Booted on Oak and hacked MMU init to use mmu_config_range() insted of memranges. Confirmed that CRCs over all page tables before and after the change are equal.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2015-04-14CBFS: Automate ROM image layout and remove hardcoded offsetsJulius Werner
Non-x86 boards currently need to hardcode the position of their CBFS master header in a Kconfig. This is very brittle because it is usually put in between the bootblock and the first CBFS entry, without any checks to guarantee that it won't overlap either of those. It is not fun to debug random failures that move and disappear with tiny alignment changes because someone decided to write "ORBC1112" over some part of your data section (in a way that is not visible in the symbolized .elf binaries, only in the final image). This patch seeks to prevent those issues and reduce the need for manual configuration by making the image layout a completely automated part of cbfstool. Since automated placement of the CBFS header means we can no longer hardcode its position into coreboot, this patch takes the existing x86 solution of placing a pointer to the header at the very end of the CBFS-managed section of the ROM and generalizes it to all architectures. This is now even possible with the read-only/read-write split in ChromeOS, since coreboot knows how large that section is from the CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be changed on systems that place other data next to coreboot/CBFS in ROM). Also adds a feature to cbfstool that makes the -B (bootblock file name) argument on image creation optional, since we have recently found valid use cases for CBFS images that are not the first boot medium of the device (instead opened by an earlier bootloader that can already interpret CBFS) and therefore don't really need a bootblock.

2015-04-10serial: Combine Tegra and Rockchip UARTs to generic 8250_mmio32Julius Werner
We have two drivers for a 100%-identical peripheral right now, mostly because we couldn't come up with a good common name for it back when we checked it in. That seems like a pretty silly reason in the long run. Both Tegra and Rockchip SoCs contain UARTs that use the common 8250 register interface (at least for the very basic byte-per-byte transmit and receive parts we care about), memory-mapped with a 32-bit register stride. This patch combines them to a single 8250_mmio32 driver (which also fixes a problem when booting Rockchip without serial enabled, since that driver forgot to check for serial initialization when registering its console drivers). The register accesses are done using readl/writel (as Rockchip did before), since the registers are documented as 32-bit length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce APB accesses to have the full word length. Also fixed checkpatch stuff. A day may come when we can also merge this driver into the (completely different, with more complicated features and #ifdefs) 8250 driver for x86 (which has MMIO support for 8-bit register stride only), both here and in coreboot. But it is not this day. This day I just want to get rid of a 99% identical file without expending too much effort.

2015-04-08arm: Dump additional fault registers in abort handlersJulius Werner
Paging code is tricky and figuring out what is wrong with it can be a pain. This patch tries to ease the burden by giving a little more information for prefetch and data aborts, dumping the Instruction Fault Address Register (IFAR), Instruction Fault Status Register (IFSR) and Auxiliary Instruction Fault Status Register (AIFSR) or the respective Data registers. These contain additional information about the cause of the abort (internal/external, write or read, fault subtype, etc.) and the faulting address. BUG=None TEST=I have read through enough imprecise asynchronous external abort reports with this patch that I learned the bit pattern by heart.

2015-03-23libpayload: usb: xhci: set ENT flag in last Normal TRBSourabh Banerjee
If a TD is comprised of one or more Normal TRBs and terminated with an Event Data TRB, then the transition to the Idle state (and associated Stream state save) could occur after all the data for the TD has been moved (e.g. after Transfer Event TRBs have been executed), but before the Event Data TRB is executed. Under these conditions, the execution of the Event Data TRB is necessary to complete the TD, otherwise it does not occur until the next time the Stream is scheduled. This could lead to the lock up. The Evaluate Next TRB(ENT) flag provides a means of forcing the execution of a terminating Event Data TRB. Setting ENT flag in last Normal TRB makes the xHC to evaluate the Even Data TRB.

Additionally, we also: 1) Initialize DMA memory on our own depending upon the memory map. It ensures that the DMA buffer is placed in 32-bit memory.

2015-03-21libpayload arm64: Add library helpersFurquan Shaikh
Add library helpers to access standard arm64 registers. This library also provides functions to directly read/write register based on current el. So, rest of the code doesnt need to keep checking the el and call appropriate function based on that.
