do_smhload: fix return code

2017-03-10T00:52:14Z

do_smhload was using a ulong to store the return value from smh_load_file. That returns an int, where -1 indicates an error. As a ulong will never be negative, smh_load_file errors were not detected and so_smhload always returned zero. Also, when errors were spotted, do_smhload was returning 1, rather than the enumeration CMD_RET_FAILURE (which is also 1). Signed-off-by: Ryan Harkin Reviewed-by: Linus Walleij

armv8: spl: Call spl_relocate_stack_gd for ARMv8

2017-03-02T02:28:34Z

As part of the startup process for boards using the SPL, we need to call spl_relocate_stack_gd. This is needed to set up malloc with its DRAM buffer. Signed-off-by: Philipp Tomsich Reviewed-by: Andre Przywara Reviewed-by: Simon Glass

arm64: fix comment in relocate_64.S

There are two typos in the comment "invalide i-cache is enabled". We can fix it by invalide -> invalidate is -> if Or, if we want to match the comment to the code, we can say "skip invalidating i-cache if disabled". Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass

ARM: Default to using optimized memset and memcpy routines

2017-01-20T20:38:01Z

We have long had available optimized versions of the memset and memcpy functions that are borrowed from the Linux kernel. We should use these in normal conditions as the speed wins in many workflows outweigh the relatively minor size increase. However, we have a number of places where we're simply too close to size limits in SPL and must be able to make the size vs performance trade-off in those cases.

For 64-bit kernel, there is a warning about x1-x3 nonzero in violation of boot protocol. To fix this issue, input argument 4 is added for armv8_switch_to_el2 and armv8_switch_to_el1. The input argument 4 will be set to the right value, such as zero. Signed-off-by: Alison Wang Reviewed-by: Alexander Graf Tested-by: Ryan Harkin Tested-by: Michal Simek Reviewed-by: York Sun

ARM: boot0 hook: remove macro, include whole header file

2017-01-04T15:37:41Z

For prepending some board specific header area to U-Boot images we were so far including a header file with a macro definition containing the actual header specification. This works fine if there are just a few statements and if there is only one alternative. However adding more complex code quickly gets messy with this approach, so let's just drop that intermediate macro and let the #include actually insert the code directly. This converts the callers and the callees, but doesn't change anything at this point. Signed-off-by: Andre Przywara Reviewed-by: Simon Glass Tested-by: Steve Rae Reviewed-by: Jagan Teki
