* Merge tag 'signed-efi-next' of git://github.com/agraf/u-bootTom Rini2016-10-1925-551/+165
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch queue for efi - 2016-10-19 Highlights this time around: - Add run time service (power control) support for PSCI (fixed in v3) - Add efi gop pointer exposure - SMBIOS support for EFI (on ARM) - efi pool memory unmap support (needed for 4.8) - initial x86 efi payload support (fixed up in v2) - various bug fixes Signed-off-by: Tom Rini <trini@konsulko.com> Conflicts: include/tables_csum.h
| * efi_loader: Rename EFI_RUNTIME_{TEXT, DATA} to __efi_runtime{, _data}Alexander Graf2016-10-191-6/+6
| | | | | | | | | | | | | | | | | | | | | | Compiler attributes are more commonly __foo style tags rather than big upper case eye sores like EFI_RUNTIME_TEXT. Simon Glass felt quite strongly about this, so this patch converts our existing defines over to more eye friendly ones.

| * x86: efi: Add EFI loader support for x86Simon Glass2016-10-193-1/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | Add the required pieces to support the EFI loader on x86. Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application is supported. If a 64-bit kernel must be booted, U-Boot supports this directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a payload for both 32-bit and 64-bit EFI.

On these systems, we do not need to implement system reset manually, but can instead rely on higher level firmware to deal with it.

That means we don't really need to expose the hypercall variants of them. This patch leaves the code in, but makes the code explicit enough to have the compiler optimize it out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM CPUs can architecturally (speculatively) prefetch completely arbitrary normal memory locations, as defined by the current translation tables. The current MMU configuration for 64-bit Tegras maps an extremely large range of addresses as DRAM, well beyond the actual physical maximum DRAM window, even though U-Boot only needs access to the first 2GB of DRAM; the Tegra port of U-Boot deliberately limits itself to 2GB of RAM since some HW modules on at least some 64-bit Tegra SoCs can only access a 32-bit physical address space. This change reduces the amount of RAM mapped via the MMU to disallow the CPU from ever speculatively accessing RAM that U-Boot will definitely not access. This avoids the possibility of the HW raising SError due to accesses to always-invalid physical addresses.
