acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

33554fcec9 rockchip: rk3288: Fix wrong TPL_TEXT_BASE
TPL offset 0xff704004 is unaligned address which is adding nearest
8-bytes for next instruction, So  0xff704004 is adding 0x20 for
proper alignment which is causing the next instruction data
0xefffffff is moved.

-----------------------------

b4d23f7643 rockchip: add support for enter to bootrom download mode
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.

4d9253fb76 rockchip: rk3188: use boot0 hook to load up SPL in 2 steps
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.

b377d22264 rockchip: boot0 hook: support early return for RK3188/RK3066-style BROM
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.

- 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.

ee14d29db0 rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPL
The back-to-bootrom option is rather unfortunately named
  CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM

  CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM

To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
we need to rename it.  At the same time, we introduce a TPL_ variant of
the option to give us finer-grained control over when it should be used.

This change is motivated by our RK3368 boot process, which returns to
the boot ROM only from the TPL stage, but not from the SPL stage.

7ee16de58b rockchip: rk3399: spl: add UART0 support for SPL
The RK3399-Q7 ("Puma") SoM exposes UART0 as the Qseven UART (i.e. the
serial line available via standardised pins on the edge connector and
available on a RS232 connector).

To support boards (such as the RK3399-Q7) that require UART0 as a
debug console, we match CONFIG_DEBUG_UART_BASE and add the appropriate
iomux setup to the rk3399 SPL code.

As we are already touching this code, we also move the board-specific
UART setup (i.e. iomux setup) into board_debug_uart_init(). This will
be called from the debug UART init when CONFIG_DEBUG_UART_BOARD_INIT
is set.

As the RK3399 needs to use its board_debug_uart_init() function, we
have Kconfig enable it by default for RK3399 builds.

With everything set up to define CONFIG_BAUDRATE via defconfig and
with to have the SPL debug UART either on UART0 or UART2, the configs
for the RK3399 EVB are then update (the change for the RK3399-Q7 is
left for later to not cause issues on applying the change).

008a610b4c rockchip: rk3188: enable remap function
Most Rockchip socs have the ability to either map the bootrom or a sram
area to the starting address of the cpu by flipping a bit in the GRF.

Newer socs leave this untouched and mapped to the bootrom but the legacy
loaders on rk3188 and before enabled the remap functionality and the
current smp implementation in the Linux kernel also requires it to be
enabled, to bring up secondary cpus.

So to keep smp working in the kernel, mimic the behaviour of the legacy
bootloaders and enable the remap functionality.

3d54eabcaf rockchip: spl: RK3399: use boot0 hook to create space for SPL magic
The SPL binary needs to be prefixed with the boot magic ('RK33' for
the RK3399) on the Rockchip platform and starts execution of the
instruction word following immediately after this boot magic.

This poses a challenge for AArch64 (ARMv8) binaries, as the .text
section would need to start on the odd address, violating natural
alignment (and potentially triggering a fault for any code that
tries to access 64bit values embedded in the .text section).

A quick and easy fix is to have the .text section include the 'RK33'
magic and pad it with a boot0 hook to insert 4 bytes of padding at the
start of the section (with the intention of having mkimage overwrite
this padding with the appropriate boot magic). This avoids having to
modify the linker scripts or more complex logic in mkimage.

b47ea79219 rockchip: add option to change method of loading u-boot
If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large SPL binary. Rockchip SoC's
bootrom code has the ability to load spl and u-boot, then boot.

If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to
bootrom in board_init_f(), then bootrom loads u-boot binary.

Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

aa15038cdf rockchip: Use 'select' instead of defaults in Kconfig
Rockchip uses driver model for all subsystems. Specify this in the arm
Kconfig rather than as defaults in the Rockchip Kconfig. This means that
boards cannot turn these options off, which seems correct.

3c27b6ad54 dm: rockchip: Enable CONFIG_BLK
Enable CONFIG_BLK to move to using driver model for block devices. This
affects MMC booting in SPL, as well as MMC access in U-Boot proper.

cd3187d6b2 rockchip: move SYS_MALLOC_SIMPLE to mach-rockchip Kconfig
Commit 1eb0c03c21 added
SPL_SYS_MALLOC_SIMPLE Kconfig option and changed the way it is
evaluated.

Thus, the definitions of CONFIG_SYS_MALLOC_SIMPLE in rk3***_common.h
board configs are now incorrect because CONFIG_SPL_BUILD is enabled so
CONFIG_IS_ENABLED(SYS_MALLOC_SIMPLE) will look for SPL_SYS_MALLOC_SIMPLE
instead of SYS_MALLOC_SIMPLE.

This commit fix this enabling SPL_SYS_MALLOC_SIMPLE with the new Kconfig
option by default in rockchip-mach.

rk3036 only 4K size SRAM for SPL, so only support
timer, uart, sdram driver in SPL stage, when finish
initial sdram, back to bootrom.And in rk3036 sdmmc and
debug uart use same iomux, so if you want to boot from
sdmmc, you must disable debug uart.
