2017-11-21rockchip: add support for enter to bootrom download modeAndy Yan
Rockchip bootrom will enter download mode if it returns from spl/tpl with a non-zero value and couldn't find a valid image in the backup partition. This patch provide a method to instruct the system to back to bootrom download mode by checking the BROM_DOWNLOAD_FLAG register. As the bootrom download function relys on some modules such as interrupts, so we need to back to bootrom as early as possbile before the tpl/spl code override the interrupt configurations.

2017-11-21rockchip: back-to-bootrom: allow passing a cmd to the bootromPhilipp Tomsich
The BROM supports forcing it to enter download-mode, if an appropriate result/cmd-word is returned to it. There already is a series to support this in review, so this prepares the (newly C-version) of the back-to-bootrom code to accept a cmd to passed on to the BROM. All the existing call-sites are adjusted to match the changed function signature. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Andy Yan <andy.yan@rock-chips.com>
2017-11-21rockchip: rk3188: use boot0 hook to load up SPL in 2 stepsPhilipp Tomsich
For the RK3188, the BROM will attempt to load up the first stage image (SPL for the RK3188) in two steps: first 1KB to offset 0x800 in the SRAM and then the remainder to offset 0xc00 in the SRAM. It always enters at 0x804, though. With this changeset, the RK3188 boot removes the TPL (stub) stage and builds a single SPL binary that utilizes the early back-to-bootrom via the boot0-hook. Consequently, the passing of the saved boot params via pmu->os_reg[2] is also removed. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
2017-11-21rockchip: back-to-bootrom: replace assembly-implementation with C-codePhilipp Tomsich
The back-to-bootrom implementation for Rockchip has always relied on the stack-pointer being valid on entry, so there was little reason to have this as an assembly implementation. This provides a new C-only implementation of save_boot_params and back_to_bootrom (relying on setjmp/longjmp) and removes the older assembly-only implementation.

2017-11-21arm: provide a PCS-compliant setjmp implementationPhilipp Tomsich
The previous setjmp-implementation (as a static inline function that contained an 'asm volatile' sequence) was extremely fragile: (some versions of) GCC optimised the set of registers. One critical example was the removal of 'r9' from the clobber list, if -ffixed-reg9 was supplied. To increase robustness and ensure PCS-compliant behaviour, the setjmp and longjmp implementation are now in assembly and closely match what one would expect to find in a libc implementation.

2017-11-21arm: mark save_boot_params_ret as a functionPhilipp Tomsich
As no '.type' was set for save_boot_params_ret in start.S, binutils did not track whether it was emitted as A32 or T32. By properly marking save_boot_params_ret as a potential function entry, we can make sure that the compiler will insert the appropriate instructions for branching to save_boot_params_ret both for call-sites emitted as A32 and T32.

2017-11-21arm: make save_boot_params_ret prototype visible for AArch64Philipp Tomsich
The save_boot_params_ret() prototype (for those of us, that have a valid SP on entry and can implement save_boot_params() in C), was previously only defined for !defined(CONFIG_ARM64). This moves the declaration to a common block to ensure the prototype is available to everyone that might need it.

2017-11-21rockchip: boot0 hook: support early return for RK3188/RK3066-style BROMPhilipp Tomsich
Some Rockchip BROM versions (e.g. the RK3188 and RK3066) first read 1KB data from NAND into SRAM and executes it. Then, following a return to bootrom, the BROM loads additional code to SRAM (not overwriting the first block read) and reenters at the same address as the first time. To support booting either a TPL (on the RK3066) or SPL (on the RK3188) using this model of having to count entries, this commit adds code to the boot0 hook to track the number of entries and handle them accordingly.

2017-11-21rockchip: enable boot0-hook for all Rockchip SoCsPhilipp Tomsich
Rockchip SoCs bootrom design is like this: - First 2KB or 4KB internal memory is for bootrom stack and heap; - Then the first 4-byte suppose to be a TAG like 'RK33'; - The the following memory address end with '0004' is the first instruction load and running by bootrom; Let's use the boot0 hook to reserve the first 4-byte tag for all the Rockchip SoCs.

2017-11-21arm: boot0 hook: move boot0 hook before '_start'Philipp Tomsich
The boot0 hook on ARM does not insert its payload before the vector table. This is both a mismatch with thec comment above it and contradict usage of the boot0 hook on ARM64. To fix this (and unify the semantics for ARM and ARM64), we change the boot0-hook semantics on ARM to match those on ARM64: (1) if a boot0-hook is present it is inserted at the start of the image (2) if a boot0-hook is present, emitting the ARM vector table (and the _start) symbol are suppressed in vectors.S and the boot0-hook has full control over where and when it wants to emit these Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>

2017-11-17pylibfdt: compile pylibfdt only when dtoc/binman is necessaryMasahiro Yamada
Currently, pylibfdt is always compiled if swig is installed on your machine. It is really annoying because most of targets (excepts x86, sunxi, rockchip) do not use dtoc or binman. "checkbinman" and "checkdtoc" are wrong. It is odd that the final build stage checks if we have built necessary tools. If your platform depends on dtoc/binman, you must be able to build pylibfdt. If swig is not installed, it should fail immediately. I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be property select:ed by platforms that need them. Kbuild will descend into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
