3fb08a2138 spi: rockchip_sfc: add support for Rockchip SFC
This patch adds support for the Rockchip serial flash controller
found on the PX30 SoC. It should work for versions 3-5 of the SFC
IP, however I am only able to test it on v3.

This is adapted from the WIP SPI-MEM driver for the SFC on mainline
Linux. Note that the main difference between this and earlier versions
of the driver is that this one does not support DMA. In testing
the performance difference (performing a dual mode read on a 128Mb
chip) is negligible. DMA, if used, must also be disabled in SPL
mode when using A-TF anyway.

475bb949ed rockchip: Fix u-boot-rockchip.bin build
Currently there are a few arm32 rockchip board configs that don't
generate u-boot-rockchip.bin when running make because CONFIG_BINMAN
is not enabled. This patch changes CONFIG_ARCH_ROCKCHIP to also select
CONFIG_BINMAN if CONFIG_SPL and !CONFIG_ARM64.

Example builds that don't generate u-boot-rockchip.bin without this
patch:

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make kylin-rk3036_defconfig
make

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make rock_defconfig

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-

b212ad24a6 rockchip: Fix MMC boot order
Basically all, i.e. rk3036.dtsi, rk3128.dtsi, rk3xxx.dtsi, rk322x.dtsi,
rk3288.dtsi, rk3308-u-boot.dtsi, rk3328-u-boot.dtsi, rk3399-u-boot.dtsi
and px30-u-boot.dtsi Rockchip SoC devicetrees which have mmc indexes
are defining eMMC as mmc0 and sdmmc as mmc1.
This means that the rule to try to boot from the SD card first is ignored,
which as per comment is what we want and is important for distros, which
rely on that.

Fix this by setting the correct mmc index, i.e. first from mmc1 (SD card),
second from mmc0 (eMMC).

610083e547 arm: imx8ulp: Enable full L2 cache in SPL
SRAM2 is half L2 cache and default to SRAM after system boot.
To enable the full l2 cache (512KB), it needs to reset A35 to make
the change happen.

So re-implement the jump entry function in SPL:
1. configure the core0 reset vector to entry (ATF)
2. enable the L2 full cache
3. reset A35
So when core0 up, it runs into ATF. And we have 512KB L2 cache working.
