2018-08-03armv8: make SPL exception vectors optionalAndre Przywara
Even though the exception vector table is a fundamental part of the ARM architecture, U-Boot mostly does not make real use of it, except when crash dumping. But having it in takes up quite some space, partly due to the architectural alignment requirement of 2KB. Since we don't take special care of that, the compiler adds a more or less random amount of padding space, which increases the image size quite a bit, especially for the SPL. On a typical Allwinner build this is around 1.5KB of padding, plus 1KB for the vector table (mostly padding space again), then some extra code to do the actual handling. This amounts to almost 10% of the maximum image size, which is quite a lot for a pure debugging feature. Add a Kconfig symbol to allow the exception vector table to be left out of the build for the SPL. For now this is "default y" for everyone, but specific defconfigs, platforms or .config files can opt out here at will, to mitigate the code size pressure we see for some SPLs. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
2018-08-03armv8: Reduce exception handling codeAndre Przywara
The arm64 exception handling code is quite big, mostly due to architectural alignment requirements. Each exception entry spans 32 instructions, which sounds generous, but is too small to fit all of the save/branch/restore code in there. So at the moment we use only four instructions, branching into shared save and restore routines. To not leave the space for those remaining 28 instructions wasted, let's split the save and restore routines and stuff them into the gaps. This saves about 250 bytes of code, which is helpful for those tight SPLs. Signed-off-by: Andre Przywara <andre.przywara@arm.com>

2018-07-25efi_loader: Rename sections to allow for implicit dataAlexander Graf
Some times gcc may generate data that is then used within code that may be part of an efi runtime section. That data could be jump tables, constants or strings. In order to make sure we catch these, we need to ensure that gcc emits them into a section that we can relocate together with all the other efi runtime bits. This only works if the -ffunction-sections and -fdata-sections flags are passed and the efi runtime functions are in a section that starts with ".text". Up to now we had all efi runtime bits in sections that did not interfere with the normal section naming scheme, but this forces us to do so. Hence we need to move the efi_loader text/data/rodata sections before the global *(.text*) catch-all section. With this patch in place, we should hopefully have an easier time to extend the efi runtime functionality in the future. Signed-off-by: Alexander Graf <agraf@suse.de> [agraf: Fix x86_64 breakage]

2018-07-03arm: timer: sunxi: add Allwinner timer erratum workaroundAndre Przywara
The Allwinner A64 SoCs suffers from an arch timer implementation erratum, where sometimes the lower 11 bits of the counter value erroneously become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and backwards, with the latter one often showing weird behaviour. Port the workaround proposed for Linux to U-Boot and activate it for all A64 boards. This fixes crashes when accessing MMC devices (SD cards), caused by a recent change to actually use the counter value for timeout checks.

2018-06-14efi_loader: Convert runtime reset from switch to if statementsAlexander Graf
We currently handle the UEFI runtime reset / power off case handling via a switch statement. Compilers (gcc in my case) may opt to handle these via jump tables which they may conveniently put into .rodata which is not part of the runtime section, so it will be unreachable when executed. Fix this by just converting the switch statement into an if/else statement. It produces smaller code that is faster and also correct because we no longer refer .rodata from efi runtime code.

2018-05-09armv8/fsl-lsch2: make the workaround for PIN MUX erratum A010539 robustHou Zhiqiang
Mask HRESET_B after cleared the the RCW_SRC, because in the workaround we override the RCW_SRC and if HRESET_B is issued after the override then SoC cannot find valid RCW as the RCW_SRC was overwritten and result in hang. So we need to mask HRESET_B in case user asserts it, and the PORESET_B should be asserted which leads to resampling of cfg_rcw_src pins and loading of correct RCW_SRC.

2018-05-09armv8: sec_firmware: Remove JR3 from device tree node in all casesRuchika Gupta
JR3 was getting removed from device tree only if random number generation was successful. However, if SEC firmware is present, JR3 should be removed from device tree node irrespective of the random seed generation as SEC firmware reserves it for it's use. Not removing it in case of random number generation failure causes the kernel to crash. Random number generation was being called twice. This is not required. If SEC firmware is running, SIP call can be made to the SEC firmware to get the random number. This call itself would return failure if function is not supported.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
