To avoid diverging too much on an actively developed code base, keep the changes to a separate commit that can be downstreamed more easily: - removed unused includes - gave kevin board a "Kevin" part number - marked RW_LEGACY as CBFS region (to follow up upstream changes) - moved romstage entry point to SoC code (instead of encouraging per-board copy pasta) Change-Id: Ief0c8db3c4af96fe2be2e2397d8874ad06fb6f1f Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: https://review.coreboot.org/14362 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-04-07edid: Make framebuffer row alignment configurableJulius Werner
Our EDID code had always been aligning the framebuffer's bytes_per_line (and x_resolution dependent on that) to 64. It turns out that this is a controller-dependent parameter that seems to only really be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper function to calculate bits-per-pixel dependent values) probably actually broke this for some other controllers by applying the alignment too widely. This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).

2016-03-24edid: Add helper function to calculate bits-per-pixel dependent valuesJulius Werner
Coreboot and most payloads support three basic pixel widths for the framebuffer. It assumes 32 by default, but several chipsets need to override that value with whatever else they're supporting. Our struct edid contains multiple convenience values that are directly derived from this (and other properties), so changing the bits per pixel always requires recalculating all those dependents in the chipset code. This patch provides a small convenience wrapper that can be used to consistently update the whole struct edid with a new pixel width instead, so we no longer need to duplicate those calculations everywhere. BUG=None TEST=Booted Oak in all three pixel widths (which it conveniently all supports), confirmed that images looked good.

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

2015-09-22linking: link bootblock.elf with .data and .bss sections againAaron Durbin
Currently coreboot expects the loader to clear the bss section for all stages. i.e. stages don't clear their own bss. On ARM SoCs the BootROM would be responsible for this. To do that one needs to include the bss section data (all zeros) in the bootblock.bin file. This was previously being attempted by keeping the .bss info in the .data section because objcopy happened zero out non-file allocated data section data. Instead go back to linking bootblock with the bss section but mark the bss section as loadable allocatable data. That way it will be included in the binary properly when objcopy -O binary is emplyed. Also do the same for the data section in the case of no non-zero object values are in the data section. Without this change the trick of including .bss in .data was not working when there wasn't a non-zero value object in the data section. BUG=None BRANCH=None TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains the cleared bss.

The reasoning is that Chrome OS doesn't always do display initialization during startup. It's runtime dependent.

Instead provide one function, display_init_required(), that provides the policy for determining display initialization action. For Chrome OS devices this function honors vboot_skip_display_init() and all other configurations default to initializing display.

It also renames the enums to sound a little more sensible in other contexts (more on that in the follow-up patches). VOP_MODE_AUTO is added to the mode enum which will make it explicit that a board can support either. In AUTO_MODE we will try EDP first and then fallback to HDMI. Other modes can be set to force a certain behavior such as HDMI-only on Mickey where it doesn't make sense to try EDP. A follow-up patch will add logic for when we explicitly don't want to probe for any display (headless devices).

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.

2015-04-22rockchip/rk3288: Fix operator precedence error in LPDDR initJulius Werner
Upstream coreboot regularly runs Coverity over the code base. Turns out that's a good idea since it's really easy to screw yourself over with a missing parenthesis and some unfortunately deceptive line breaking. This patch fixes a bug in LPDDR3 initialization due to an incorrect operator precedence assumption ( ?: does not bind stronger than | ). In effect, instead of setting MR11[1:0] to 0b11 or 0b00 based on ODT, we're unconditionally setting MR0[1:0] to 0b11. Thankfully, MR0[1:0] seems to contain read-only bits so this might have not been a problem when ODT is off (which is currently true for all LPDDR boards). Also adding a redundant LPDDR_OP() around the 0 to make the intent clearer and changing 3 and 0 to 0x3 and 0x0 to make it more obvious that these are bit masks (right?).
