Patch set updated for coreboot: 0299733 exynos5420: re-factor the SDMMC GPIO config routines

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.

Patch set updated for coreboot: a0f2d19 Pit: graphics

Patrick Georgi (patrick(a)georgi-clan.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4432 -gerrit commit a0f2d19bd009a963c414dc37247fca47d3ad311b Author: Ronald G. Minnich <rminnich(a)google.com> Date: Thu Aug 1 11:38:05 2013 -0700 Pit: graphics 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.

Patch set updated for coreboot: 42e79f6 ARM: Remove (NOLOAD) from the .car section
by Patrick Georgi 21 Dec '13

21 Dec '13

Patrick Georgi (patrick(a)georgi-clan.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4435 -gerrit commit 42e79f668e75ac3fe3370c97fb7dd2efcec52b21 Author: Gabe Black <gabeblack(a)google.com> Date: Tue Aug 6 04:30:13 2013 -0700 ARM: Remove (NOLOAD) from the .car section On ARM, if the .car section is marked as NOLOAD, there's nothing that sets it to zero. Some code in the cbmem console depends on a global variable being zero initially, and if that's not true bad things happen.
