arm/lib/bootm.c: keep ARM v7M in thumb mode during boot_jump_linux()

2017-04-27T20:49:08Z

On ARM v7M, the processor will return to ARM mode when executing a blx instruction with bit 0 of the address == 0. Always set it to 1 to stay in thumb mode. Tested on STM32f746-disco board Similar commit: f99993c10882f7dc8ec35993d5febe59aac01e6a Author: Matt Porter Signed-off-by: Patrice Chotard

Remove various unused interrupt related code

2017-04-07T00:42:18Z

With d53ecad92f06 some unused interrupt related code was removed. However all of these options are currently unused. Rather than migrate some of these options to Kconfig we just remove the code in question. The only related code changes here are that in some cases we use CONFIG_STACKSIZE in non-IRQ related context. In these cases we rename and move the value local to the code in question. Fixes: d53ecad92f06 ("Merge branch 'master' of git://git.denx.de/u-boot-sunxi") Signed-off-by: Tom Rini

arm: bootm: Add dm_remove_devices_flags() call to announce_and_cleanup()

2017-04-05T02:15:10Z

This patch adds a call to dm_remove_devices_flags() to announce_and_cleanup() so that drivers that have one of the removal flags set (e.g. DM_FLAG_ACTIVE_DMA_REMOVE) in their driver struct, may do some last-stage cleanup before the OS is started.

arm: Migrate SYS_THUMB_BUILD to Kconfig, introduce SPL_SYS_THUMB_BUILD

2017-03-19T00:28:01Z

Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for various reasons. We also have cases where we only build SPL in Thumb2 mode due to size constraints and wish to build the rest of the system in ARM mode. So in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to control if we build everything or just SPL (or in theory, just U-Boot) in Thumb2 mode.

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

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

2017-02-08T21:24:27Z

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
