2013-07-15beaglebone: Put some code in romstage.c so we can tell if it ran.Gabe Black
The placeholder code in beaglebone's romstage.c didn't do anything, it just immediately tried to load the RAM stage and jump into it. That doesn't currently work, and there's no indication whether you actually successfully got into the ROM stage or not. This change adds a few lines which initialize the console and say "Hi" so that we can tell that the ROM stage is running.

2013-07-15ARM: Define custom ELF headers for ARM.Gabe Black
At least when building with the gnu toolchain, the headers the linker automatically generate save space for the actual ELF headers in one of the loadable segments. This creates two problems. First, the data you intended to be at the start of the image doesn't actually show up there, it's actually the ELF headers. Second, the ELF headers are essentially useless for firmware since there's currently nothing to tell you where they are, and even if there was, there isn't much of a reason to look at them. They're useful in userspace for, for instance, the dynamic linker, but not really in firmware. This change adds a PHDRS construct to each of the linker scripts used on ARM which define a single segment called to_load which does not have the flag set which would tell the linker to put headers in it. The first section defined in the script has ": to_load" to tell the linker which segment to put it in, and from that point on the other sections go in there by default.

The vendor and part name from coreboot is normally stored in these SMBIOS structure fields, but it can be useful to override them.

Since EC protocol v3, the packet format will be the same for all buses (inclding I2C, SPI, and LPC). That will simplify the implementation in each individual bus driver source file. To prepare for that, we will move the protocol part into crosec_proto.c: crosec_command_proto, with bus driver in callback "crosec_io".

The 5420 clock code still had a data structure in it for the 5250 clock registers which was used by some of the clock functions. That caused some clocks to be configured incorrectly, specifically the i2c clock which was running at about 80KHz instead of about 600KHz as configured by U-Boot. Also, the registers and bit positions used to set up the SPI bus were not consistent with U-Boot, and if the bus clock rate were set to 50MHz, a rate which has historically worked on snow, loading would fail. With these fixes the clock rate can be set to 50MHz and the device boots as much as is expected. I haven't yet measured the actual frequency of the bus to verify that it's now being calculated correctly.

2013-07-10exynos5250: De-switch-ify the pinmux configuration code.Gabe Black
The pinmux code for the exynos5250 was all bundled into a single, large function which contained a switch statement that would set up the pins for different peripherals within the SOC. There was also a "flags" parameter, the meaning of which, if any, depended on which peripheral was being set up. There are several problems with that approach. First, the code is inefficient in both time and space. The caller knows which peripheral it wants to set up, but that information is encoded in a constant which has to be unpacked within the function before any action can be taken. If there were a function per peripheral, that information would be implicit. Also, the compiler and linker are forced to include the entire function with all its cases even if most of them are never called. If each peripheral was a function, the unused ones could be garbage collected. Second, it would be possible to try to set up a peripheral which that function doesn't know about, so there has to be additional error checking/handling. If each peripheral had a function, the fact that there was a function to call at all would imply that the call would be understood. Third, the flags parameter is fairly opaque, usually doesn't do anything, and sometimes has to have multiple values embedded in it. By having separate functions, you can have only the parameters you actually want, give them names that make sense, and pass in values directly. Fourth, having one giant function pretends to be a generic, portable API, but in reality, the only way it's useful is to call it with constants which are specific to a particular implementation of that API. It's highly unlikely that a bit of code will need to set up a peripheral but have no idea what that peripheral actually is. Call sights for the prior pinmux API have been updated. Also, pinmux initialization within the i2c driver was moved to be in the board setup code where it really probably belongs. The function block that implements the I2C controller may be shared between multiple SOCs (and in fact is), and those SOCs may have different pinmuxes (which they do). Other places this same sort of change can be made are the pinmux code for the 5420, and the clock configuration code for both the 5250 and the 5420.

Without special annotation, the assembler and linker don't know that those symbols are functions which need special handling so that ARM/thumb issues are handled properly. This change adds that annotation which gets those functions working in Coreboot which is compiled as thumb. Libpayload and depthcharge are compiled as ARM so they don't *need* the annotation since it just works out in ARM mode, but it's the safe thing to do in case we change that in the future. We should explicitly select ARM vs. thumb when assembling assembly files to be consistent across builds and toolchains.

2013-07-10exynos5420: Clear the framebuffer before making it uncacheableStefan Reinauer
If we clear the framebuffer and then flush it back to memory using cache operations, the writes are going to be full cachelines at a time. If we make it uncacheable first, the writes will be serialized writes of whatever sized chunks memset uses, probably 4 bytes or less.

2013-07-10exynos5420: Simplify the graphics code by eliminating the unused color mapStefan Reinauer
The code that allocated space for the framebuffer was adding space for a vestigial color map which was never used. It was also passing around a structure which was used to calculate a single value which was already known when that structure was put together. Eliminate the extra space, and pass the single value instead of the structure.

2013-07-10exynos5420: Fix some problems with the clock management code.Gabe Black
The code which figured out the rate of the input clock to a peripheral was doing several things wrong. First, it was using the wrong values when determing what the source of a clock was set to. Second, it was using the wrong offset into that register to find the current source setting. This change fixes the constants which select a clock source which get some more things working, but doesn't attempt to fix the bit position table.

2013-07-10armv7: Reserve space BL1 and checksum header by specifying bootblock offset.Hung-Te Lin
Not all ARM systems need "BL1", and the layout of BL* and bootblock may be different (ex, Exynos 5250 may use a new BL1 with variable length checksum header). To support that better, define the real base address (and ROM offset) of boot block, and then we can post-processing ROM image file by filling data / checksum and any other information.

2013-07-10cpu: Add CPU microcode file to cbfs with 16-byte alignmentAaron Durbin
On x86 there is a 16-byte alignment requirement for the addresses containing the CPU microcode. The cbfs files containing the microcode are used in memory-mapped fashion when loading new mircocode. Therefore, the data payload's address/offset of a cbfs file in flash dictates the resulting alignment. Fix this by processing the CPU microcode cbfs file separately as it uses $(CBFSTOOL) to find the proper location within the provided rom image.

2013-07-10ec: Add romstage function for checking and rebooting ECDuncan Laurie
Now that we are executing VbInit() in coreboot we can end up in a situation where the recovery reason is consumed during VbInit (end of romstage) and then the EC is rebooted to RO during ramstage EC init, thereby losing the recovery reason. Two possiblities are to remove the EC check+reboot from ramstage and let it happen in depthcharge. This however means that the system has to boot all the way into depthcharge and then reboot the EC and the system again. Instead if we do a check in romstage before VbInit() is called then we can reboot the EC into RO early and avoid booting all the way to depthcharge first. This change adds a ramstage version the EC init function and calls it from the shared romstage code immediately after the PCH decode windows are setup.
