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.

2017-11-21arm: 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>

2017-11-20Makefile: Correct SPL/TPL/DTB build race conditionM. Vefa Bicakci
When building on a multi-core machine for an SPL-enabled board that also uses CONFIG_OF_EMBED, the following error can be encountered due to a race condition: make[3]: *** No rule to make target 'spl/dts/dt.dtb.o', needed by 'spl/dts/built-in.o'. Stop. ../scripts/Makefile.spl:364: recipe for target 'spl/dts' failed make[2]: *** [spl/dts] Error 2 make[2]: *** Waiting for unfinished jobs.... A reliable way to trigger this race condition is to add "sleep 60" to the end of the "arch-dtbs" rule's recipe in "dts/Makefile" and to build U-Boot against a board which uses the CONFIG_OF_EMBED and CONFIG_SPL options using "make -j8" or a similar command. This commit corrects this race condition via the use of CONFIG_OF_EMBED in the same way that commit 3c00a2c8b5e2 ("Makefile: Correct dependency race condition with TPL") and commit 054b3a1e80fc ("dm: Makefile: Build of-platdata before SPL") use CONFIG_OF_SEPARATE.

2017-11-20dra7x: fastboot: Increase recovery partition sizePraneeth Bajjuri
As per current android recommendation https://source.android.com/devices/architecture/kernel/modular-kernels 1. Android recovery mode should contain both SOC and ODM kernel modules in the recovery partition. 2. If a kernel module is required both in recovery and normal boot mode, the module has to be located in recovery and vendor partition seperately. 3. Kernel modules used in recovery mode should be independent of vendor and odm partition 4. Recovery image should contain atleast storage, display, keypad, battery and pmic modules. Due to these requirements, recovery image size has increased to >10MB. This patch is to increase recovery partition size for TI devices so that we dont see such flashing error log: sending 'recovery' (12560 KB)... OKAY [ 0.436s] writing 'recovery'...
