2018-01-10build: Drop CONFIG_SPL_BUILD guards in some casesTom Rini
Given gcc-6.1 and later we can now safely have strings discarded when the functions are unused. This lets us drop certain cases of not building something so that we don't have the strings brought in when the code was discarded. Simplify the code now by dropping guards we don't need now.

2018-01-09arm: Exercise v7_arch_cp15_set_acr even without errata fixupsSiarhei Siamashka
By applying this patch, we are ensuring that the code paths responsible for applying errata workarounds are also exercised on CPU revisions, which actually don't need these workarounds. Only CONFIG_ARM_ERRATA_621766, CONFIG_ARM_ERRATA_454179, CONFIG_ARM_ERRATA_725233 and CONFIG_ARM_ERRATA_430973 are covered by this patch (Cortex-A8). This improves code coverage when testing U-Boot builds on newer hardware. In particular, the problematic commit 00bbe96ebabb ("arm: omap: Unify get_device_type() function") would break both BeageBoard and BeagleBoard XM rather than just older BeagleBoard. As an additional bonus, we need fewer instructins and the SPL size is reduced. Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2017-12-04armv8: shrink exception table codeAndre Przywara
In the moment our exception entry code needs 34 instructions, so we can't use put it directly into the table entry, which offers "only" 32 instructions there. Right now we just put an unconditional branch there, then use a macro to place the 34 instructions *per entry* after that. That effectivly doubles the size of our exception table, which is quite a waste, given that we use it mostly for debugging purposes. Since the register saving part is actually identical, let's just convert that macro into a function, and "bl" into it directly from the exception slot, of course after having saved at least the original LR. This saves us about 950 bytes of code, which is quite a relief for some tight SPLs, in particular the 64-bit Allwinner ones. Signed-off-by: Andre Przywara <andre.przywara@arm.com>

2017-10-09armv8: fsl-layerscape: Allocate Secure memory from first ddr regionSumit Garg
This change is required due to trusted OS (OP-TEE) not being position independent code, it requires compile time fixed base address. To take care of this it is assumed that all layerscape armv8 platforms has minimum 2G ddr in first region. So we can have fixed address space (66 MB -> (2MB for PPA + 64MB for trusted OS)) allocated from top of first 2G ddr region and compile trusted OS with this fixed base address. But one exception here is ls1012 where we have only 1G (rdb) or 512M (frdm) ddr memory. For those we can have different fixed compile time base addresses for trusted OS.
