2013-12-21exynos5420: Configure the UART pins unconditionallyGabe Black
Configure the pins for the UART unconditionally in the mainboard code (when we know which UART to configure) instead of in the UART driver. This also means the UART will work if later software wants to use it without setting up the pins. Built and booted on pit with the serial turned off and some serial init in the kernel decompression stub fixed.

2013-12-21exynos5250: Implement support to boot with USB A-A firmware uploadJulius Werner
This patch implements the basic infrastructure required to use the USB A-A firmware upload feature on Exynos5 processors with Coreboot. It will require a corresponding host-side script that activates the feature and uploads the correct image parts in the correct order to harcoded target addresses, as described in the comments of alternate_cbfs.c. Also fixes a bug in the Google Snow mainboard where it would not correctly initialize the pinmux configuration for the SPI flash bus. During a normal SPI boot the IROM would already do that for you, but when booting from USB you have to do it yourself.

2013-12-21exynos5420: re-factor the SDMMC GPIO config routinesDavid Hendricks
The existing GPIO config routines for SDMMC0-2 are over-generalized and somewhat confusing as a result. It would work nicely if all SDMMC ports were configured in the same fashion, but there are a few exceptions. For example, the inner function runs differently if we're using 8 bits of data instead of 4, so a big chunk is skipped for SDMMC2. SDMMC0 requires SD_0_CDn to be an output rather than alternate function and must have a value set. This patch trades some verbosity for simplicy. Now the SDMMC GPIO configuration a straight-forward sequence of GPIO operations without any exceptions.

2013-12-21Pit: graphicsRonald G. Minnich
This includes the new dp code, which is better, and the fimd code, which is changed and improved. We took the chance to remove un-needed files, and also to remove some foolish u-boot habits, but not all of them. That will take time. With these changes we get graphics. Since the only mainboards we have with 16 bit graphics are 5:6:5, adjust edid.c to just use that format. If at some future time we need 4:4:4, which seems unlikely, we'll need to add a function to adjust the lb_framebuffer. Note that you can't just divine this from the EDID, as the graphics pipe format need not match the actual final format used. The EDID reading works. We've been requested to support hard-coded EDIDs and that will come in the next revision. Currently the hard-coded EDID is ignored for testing.

2013-12-06arch/x86: Do not run UPDATE-FIT if we don't include microcodeAlexandru Gagniuc
The original intention was to only run UPDATE_FIT when a microcode file was included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on hasswell, the UPDATE-FIT step was always run, even when no microcode was included, generating a build error. Instead, introduce a new variable which tells if a microcode update is added in CBFS during the build.

2013-12-05cpu: Remove BOARD_MICROCODE_CBFS_GENERATE Kconfig optionAlexandru Gagniuc
Commit * bdafcfa Add the Intel FSP 206ax CPU core support Introduced this option. This option was meant to have a board generate a CBFS file containing microcode. However, microcode generation used to be enabled by default when CPU_MICROCODE_IN_CBFS was selected. The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic default, which is not what we want. This option is misguided in the sense that it tends to introduce a non-default which had been intentionally a default. We now have to select two Kconfig options in order to generate microcode in CBFS, meaning one option is redundant.

When an INIT# is delivered to the CPU the CPU starts executing from the reset vector. However, the internal state is maintained. Therefore, check for such a condition and reset the system. Issues 'apreset warm' on the EC console. INIT# is sent and CPU notices it's not a clean reset and forces one. No hangs.
