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: 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: 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.

2017-11-21arm: 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>

This is required in the case where U-Boot is typically loaded and run at a particular address, but for some reason the RAM at that location is not available, e.g. due to memory fragmentation loading other boot binaries or firmware, splitting an SMP complex between various different OSs without using e.g. the EL2 second-stage page tables to hide the memory asignments, or due to known ECC failures.
