* arm/arm64: implement a boot header capabilityAndre Przywara2016-06-06-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SPL loaders (like Allwinner's boot0, and Broadcom's boot0) require a header before the actual U-Boot binary to both check its validity and to find other data to load. Sometimes this header may only be a few bytes of information, and sometimes this might simply be space that needs to be reserved for a post-processing tool. Introduce a config option to allow assembler preprocessor commands to be inserted into the code at the appropriate location; typical assembler preprocessor commands might be: .space 1000 .word 0x12345678 Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Steve Rae <srae@broadcom.com> Commit Notes: Please note that the current code: start.S (arm64) and vectors.S (arm) already jumps over some portion of data already, so this option basically just increases the size of this region (and the resulting binary). For use with Allwinner's boot0 blob there is a tool called boot0img[1], which fills the header to allow booting A64 based boards. For the Pine64 we need a 1536 byte header (including the branch instruction) at the moment, so we add this to the defconfig.

* ARM: fix ifdefs in ARMv8 lowlevel_init()Stephen Warren2016-05-06-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 724219a65f55 "ARM: always perform per-CPU GIC init" removed some ifdefs to unify the MULTIENTRY-vs-non-MULTIENTRY paths. However, the wrong endif was removed. This patch adds back that missing endif, and adds a new ifdef to match the endif the now-correctly-terminated block used to match against. Use "git show -U25 724219a65f55" to see enough context to make the original issue clear. In practical terms, this makes no difference to runtime behaviour. The code that was incorrectly compiled into the binary when ifndef MULTIENTRY is a no-op for other cases, since branch_if_master evaluates to a hard- coded jump. The only issues were: - A few extra instructions were added to the binary. - The comment on the endif at the very end of the function, indicating which ifdef it matched, were wrong. An alternative might be to simply fix the comment on that trailing ifdef, but that only addresses the second point above, not the first.

* ARM: always perform per-CPU GIC initStephen Warren2016-04-18-10/+0
| | | | | | | | | | | | | | | | | | The current code in ARMv8's lowlevel_init() skips the per-CPU GIC initialization ifndef CONFIG_ARMV8_MULTIENTRY. However, the per-CPU init should always occur; it's just the one-time init that should only happen on the master. Once this consideration is taken into account, the only difference between the paths when CONFIG_ARMV8_MULTIENTRY is undefined/defined is the use of branch_if_slave. Naively, any unified code would need to invoke this conditionally upon ifdef CONFIG_ARMV8_MULTIENTRY. However, branch_if_slave already checks CONFIG_ARMV8_MULTIENTRY and does nothing if it isn't defined, so we don't even need that ifdef at the call site.

| | | | | | | | | | | | | | | | | | | The idea to generate our pages tables from an array of memory ranges is very sound. However, instead of hard coding the code to create up to 2 levels of 64k granule page tables, we really should just create normal 4k page tables that allow us to set caching attributes on 2M or 4k level later on. So this patch moves the full_va mapping code to 4k page size and makes it fully flexible to dynamically create as many levels as necessary for a map (including dynamic 1G/2M pages). It also adds support to dynamically split a large map into smaller ones when some code wants to set dcache attributes. With all this in place, there is very little reason to create your own page tables in board specific files. Signed-off-by: Alexander Graf <agraf@suse.de>
