2017-04-06Remove various unused interrupt related codeTom Rini
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 <trini@konsulko.com>
2016-03-15arm: Allow EFI payload code to take exceptionsAlexander Graf
There are 2 ways an EFI payload could return into u-boot: - Callback function - Exception While in EFI payload mode, r9 is owned by the payload and may not contain a valid pointer to gd, so we need to fix it up. We do that properly for the payload to callback path already. This patch also adds gd pointer restoral for the exception path. Signed-off-by: Alexander Graf <agraf@suse.de>

2015-02-03arm: Show relocated PC/LR in the register dumpSimon Glass
If we don't know the relocation address, the raw values are not very useful. Show the pre-relocation values as well as these can be looked up in System.map, etc. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2014-10-29arm: interrupt_init: set sp in IRQ/FIQ modesGeorges Savoundararadj
Before this commit, the stack addresses for IRQ and FIQ modes, IRQ_STACK_START and FIQ_STACK_START, were computed in interrupt_init but they were not used. This commit sets the stack pointers for IRQ and FIQ modes. Signed-off-by: Georges Savoundararadj <savoundg@gmail.com> Acked-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2014-07-28ARM: add missing HYP mode constantMarc Zyngier
In order to be able to use the various mode constants (far more readable than random hex values), add the missing HYP and A values. Also update arm/lib/interrupts.c to display HYP instead of an unknown value. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2014-02-26arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

2012-10-15ARM: prevent misaligned array initsAlbert ARIBAUD
Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.

2010-10-29Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk
When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

2010-09-19ARM: add relocation supportHeiko Schocher
!! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.
