2018-09-26Merge tag 'signed-efi-next' of git://github.com/agraf/u-bootTom Rini
Patch queue for efi - 2018-09-26 A lot of goodness in this release. We're *very* close to running the UEFI Shell and SCT natively. The only missing piece are HII protocols. - FAT write support (needed for SCT) - improved FAT directory support (needed for SCT) - RTC support with QEMU -M virt - Sandbox support (run UEFI binaries in Linux - yay) - Proper UTF-16 support - EFI_UNICODE_COLLATION_PROTOCOL support (for UEFI Shell) - EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL support (for UEFI Shell) - Fix window size determination - Fix Tegra by explicitly unmapping RAM - Clean up handle entanglement - Lots of generic code cleanup [trini: Fixup merge conflict in include/configs/qemu-arm.h] Signed-off-by: Tom Rini <trini@konsulko.com>

2018-09-23sandbox: Allow to execute from RAMAlexander Graf
With efi_loader, we may want to execute payloads from RAM. By default, permissions on the RAM region don't allow us to execute from there though. So let's change the default allocation scheme for RAM to also allow execution from it. That way payloads that live in U-Boot RAM can be directly executed.

2018-09-23sandbox: Fix setjmp/longjmpAlexander Graf
In sandbox, longjmp returns to itself in an endless loop because os_longjmp() calls into longjmp() which is provided by U-Boot which again calls os_longjmp(). Setjmp on the other hand must not return because otherwise the return freees up stack elements that we need during longjmp(). The only straight forward fix that doesn't involve nasty hacks I could find is to directly link against the system setjmp/longjmp implementations. That means we just provide the compiler with hints that the symbol will be available and actually fill them out with versions from libc. This approach should be reasonably platform agnostic Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23sandbox: Enhance map_to_sysmem() to handle foreign pointersSimon Glass
At present map_sysmem() maps an address into the sandbox RAM buffer, return a pointer, while map_to_sysmem() goes the other way. The mapping is currently just 1:1 since a case was not found where a more flexible mapping was needed. PCI does have a separate and more complex mapping, but uses its own mechanism. However this arrange cannot handle one important case, which is where a test declares a stack variable and passes a pointer to it into a U-Boot function which uses map_to_sysmem() to turn it into a address. Since the pointer is not inside emulated DRAM, this will fail. Add a mapping feature which can handle any such pointer, mapping it to a simple tag value which can be passed around in U-Boot as an address.

2018-09-23sandbox: Add support for calling abort()Simon Glass
This function is useful to signal that the application needs to exit immediate. It can be caught with a debugger (e.g. gdb). Add a stub for it so that it can be called from within sandbox when an internal error occurs. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23sandbox: Align RAM buffer to the machine page sizeSimon Glass
At present the sandbox RAM buffer is not aligned to any particular address boundary. This makes the internal pointers somewhat random with respect to the associated RAM buffer addresses. Align the buffer to the page size of the machine to help with this. Note that there is a header at the start of the allocated pointer. To avoid returning a pointer which is not aligned to a page boundary, we waste almost an entire page of memory for each allocation.

2018-09-23ARM: tegra: reserve unmapped RAM so EFI doesn't use itStephen Warren
Tegra U-Boot ensures that board_get_usable_ram_top() never returns a value over 4GB, since some peripherals can't access such addresses. However, on systems with more than 2GB of RAM, RAM bank 1 does describe this extra RAM, so that Linux (or whatever OS) can use it, subject to DMA limitations. Since board_get_usable_ram_top() points at the top of RAM bank 0, the memory locations describes by RAM bank 1 are not mapped by U-Boot's MMU configuration, and so cannot be used for anything. For some completely inexplicable reason, U-Boot's EFI support ignores the value returned by board_get_usable_ram_top(), and EFI memory allocation routines will return values above U-Boot's RAM top. This causes U-Boot to crash when it accesses that RAM, since it isn't mapped by the MMU. One use-case where this happens is TFTP download of a file on Jetson TX1 (p2371-2180). This change explicitly tells the EFI code that this extra RAM should not be used, thus avoiding the crash. A previous attempt to make EFI honor board_get_usable_ram_top() was rejected. So, this patch will need to be replicated for any board that implements board_get_usable_ram_top().

Those functions are not needed during cache init and can be implemented in C. Only support the safe disabling of caches when this is required for booting an OS. Reenabling caches is much harder to implement if an optional coherency manager must be supported. As there is no real use-case anyway, dcache_enable is implemented with an error message.

2018-09-19ARM: mach-mvebu: handle fall-back to UART bootChris Packham
The bootROM in the Armada-38x (and similar) SoC has two modes for UART boot. The first is when the normal boot media is blank (or otherwise missing the kwb header). The second is when the boot sequence has been interrupted with the magic byte sequence on the UART lines. In the first mode the bootROM routine and error code register will indicate that there was an error booting from the configured media in bits 7:0. In the second mode there is no error to indicate but the boot source is provided via bits 31:28. Handle both situations so that kwboot can be used for both boot strapping a blank board and for intercepting a regular boot sequence.
