2018-12-02efi_loader: PSCI reset and shutdownHeinrich Schuchardt
When an operating system started via bootefi tries to reset or power off this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or an SMC command has to be issued. The current implementation always uses SMC. This results in crashes on systems where the PSCI firmware is implemented in the hypervisor, e.g. qemu-arm64_defconfig. The logic to decide which call is needed based on the device tree is already implemented in the PSCI firmware driver. During the EFI runtime the device driver model is not available. But we can minimize code duplication by merging the EFI runtime reset and poweroff code with the PSCI firmware driver. As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff and reset_misc routines let's move them into the same code module.

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.
