2019-03-22armv8: Disable exception vectors in SPL by defaultAlexander Graf
Commit 1416e2d2253 ("armv8: make SPL exception vectors optional") had a typo in it which effectively disabled exception handling in SPL code always. Since nobody complained, I guess we may as well disable exception handling in SPL always by default. So fix the bug to make the config option effective, but disable exception handling in SPL by default. This gets us to the same functionality as before by default, but with much less code included in the binary.

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.

2017-01-28arm64: spin-table: add more information in Kconfig helpMasahiro Yamada
This feature seems to be sometimes misunderstood. The intention is: [1] Bring the slaves into the U-Boot proper image, not SPL (unless you have a special reason to do otherwise). [2] The operation must be done in a board (SoC) specific manner since how to wake the slaves from the Boot ROM is SoC specific. [3] The slaves must enter U-Boot proper after U-Boot relocates itself because the "cpu-release-addr" property points to the relocated memory area. [2] is already explained in the help. We can make [1] even clearer by mentioning "U-Boot proper" instead of "U-Boot". [3] is missing, so I am adding it to the list. Instead, "before the master CPU jumps to the kernel" is a matter of course, so removed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is set. The SMPEN bit should be set before enabling the data cache. If not enabled, the cache is not coherent with other cores and data corruption could occur. For A57/A72, SMPEN bit enables the processor to receive instruction cache and TLB maintenance operations broadcast from other processors in the cluster. This bit should be set before enabling the caches and MMU, or performing any cache and TLB maintenance operations.

Most armv8 systems have PSCI support enabled in EL3, either through ARM Trusted Firmware or other firmware. On these systems, we do not need to implement system reset manually, but can instead rely on higher level firmware to deal with it. The exclude list seems excessive right now, but NXP is working on providing an in-tree PSCI implementation, so that all NXP systems can eventually use PSCI as well.

2016-07-14arm64: add better and more generic spin-table supportMasahiro Yamada
There are two enable methods supported by ARM64 Linux; psci and spin-table. The latter is simpler and helpful for quick SoC bring up. My main motivation for this patch is to improve the spin-table support, which allows us to boot an ARMv8 system without the ARM Trusted Firmware. Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S and the spin-table is supported in a really ad-hoc way, and I see some problems: - We must hard-code CPU_RELEASE_ADDR so that it matches the "cpu-release-addr" property in the DT that comes from the kernel tree. - The Documentation/arm64/booting.txt in Linux requires that the release address must be zero-initialized, but it is not cared by the common code in U-Boot. We must do it in a board function. - There is no systematic way to protect the spin-table code from the kernel. We are supposed to do it in a board specific manner, but it is difficult to predict where the spin-table code will be located after the relocation. So, it also makes difficult to hard-code /memreserve/ in the DT of the kernel. So, here is a patch to solve those problems; the DT is run-time modified to reserve the spin-table code (+ cpu-release-addr). Also, the "cpu-release-addr" property is set to an appropriate address after the relocation, which means we no longer need the hard-coded CPU_RELEASE_ADDR.

2015-03-09armv8/vexpress64: make multientry conditionalLinus Walleij
While the Freescale ARMv8 board LS2085A will enter U-Boot both on a master and a secondary (slave) CPU, this is not the common behaviour on ARMv8 platforms. The norm is that U-Boot is entered from the master CPU only, while the other CPUs are kept in WFI (wait for interrupt) state. The code determining which CPU we are running on is using the MPIDR register, but the definition of that register varies with platform to some extent, and handling multi-cluster platforms (such as the Juno) will become cumbersome. It is better to only enable the multiple entry code on machines that actually need it and disable it by default. Make the single entry default and add a special ARMV8_MULTIENTRY KConfig option to be used by the platforms that need multientry and set it for the LS2085A. Delete all use of the CPU_RELEASE_ADDR from the Vexpress64 boards as it is just totally unused and misleading, and make it conditional in the generic start.S code. This makes the Juno platform start U-Boot properly. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
