Caleb Connolly authoredSince removing reset_cpu() in mach-snapdragon, all Qualcomm platforms now depend on CONFIG_SYSRESET and will fail to build without it. Move the dependency from qcom_defconfig to kconfig so that we use SYSRESET for all platforms. Fixes: 61a1a1b8 ("mach-snapdragon: use PSCI sysreset driver") Signed-off-by:

If we try to enable a gate clock that doesn't exist, we used to just fail silently. This may make sense for early bringup of some core peripherals that we know are already enabled, but it only makes debugging missing clocks more difficult. Bubble up errors now that qcom_gate_clk_en() can return an error code to catch any still-missing clocks and make it easier to find missing ones as more complicated peripherals are enabled.

Caleb Connolly <caleb.connolly@linaro.org> -
Most MSM8916 devices shipped without PSCI support. The history is quite nuanced (a good overview can be found in [1]), but the end result is that the upstream DTs for this SoC pretend that PSCI exists, and it's expected that the bootloader handles the case where it doesn't. This is codified by the de-facto bootloader for MSM8916 devices, lk2nd [2]. So we handle it here by deleting the /psci node if we detect the absence of PSCI. We need to do this early to ensure sysreset works correctly, since the PSCI firmware driver is PRE_RELOC and binds the PSCI sysreset driver. Additionally, show_psci_version is updated to check that PSCI exists. Currently this banner outputs "PSCI: 65535.65535" on devices without PSCI support, which isn't very useful :) [1]: https://github.com/msm8916-mainline/linux/issues/388 [2]: https://github.com/msm8916-mainline/lk2nd/blob/8183ea2/lk2nd/smp/spin-table/spin-table.c#L237 Signed-off-by:

qcom_parse_memory is updated to return a -ENODATA error if the passed FDT does not contain a /memory node, or that node is incomplete (size=0) board_fdt_blob_setup first tries to call qcom_parse_memory with the internal FDT (if present+valid). If that fails, it tries again with the external FDT (again, if present+valid). When booting with an internal FDT from upstream, it's likely that this change results in a slight performance hit, since virtually all upstream qcom DTs lack a fully specified memory node. The impact should be negligible, though. qcom_parse_memory was given a detailed docstring adapted from Caleb's original commit message that introduced the function. Reviewed-by:

msm_rng_enable is supposed to skip writing to LFSR_CFG + CONFIG registers in the PRNG_ block if PRNG_CONFIG_HW_ENABLE is already set. The logic to test for this was inverted. Without this fix, the driver was causing SError aborts on my MSM8916 device. Stephan Gerhold suggested this was probably because TZ has marked this as a protected register, since it would also be using it for RNG.

This fixture name is quite long and results in lots of verbose code. We know this is U-Boot so the 'u_boot_' part is not necessary. But it is also a bit of a misnomer, since it provides access to all the information available to tests. It is not just the console. It would be too confusing to use con as it would be confused with config and it is probably too short. So shorten it to 'ubman'. Signed-off-by:

Up to now we configure the entire memory space for U-Boot as RWX. For modern architectures and security requirements, it's better to map the memory properly. This pull request adds basics support for mapping the U-Boot binary with proper (RO, RW, RW^X) memory permissions on aarch64 right after we relocate U-Boot in the top of DRAM. It's worrth noting that the linker script annotations are only added for the aarch64 architecture. We can, in the future, try to unify the linker -- at least for the architectures that have enough in common and expand this

Now that we have everything in place switch the page permissions for .rodata, .text and .data just after we relocate everything in top of the RAM. Unfortunately we can't enable this by default, since we have examples of U-Boot crashing due to invalid access. This usually happens because code defines const variables that it later writes. So hide it behind a Kconfig option until we sort it out. It's worth noting that EFI runtime services are not covered by this patch on purpose. Since the OS can call SetVirtualAddressMap which can relocate runtime services, we need to set them to RX initially but remap them as RWX right before ExitBootServices.
