TPL max size is limited to 184 KB, SPL is loaded to 0x0 and TF-A is
loaded to 0x40000, this limit SPL max size to 256 KB. With BootRom only
reading first 2 KB per 4 KB page of SPI flash, 880 KB may be needed for
TPL+SPL in a worst-case scenario. (184 KB + 256 KB) x 2 = 880 KB
Use 0xE0000 (896 KB) as the payload offset in SPI flash, this allows
for a payload of 3168 KB before env offset start to overlap.
Also add CONFIG_ROCKCHIP_SPI_IMAGE=y to build a bootable SPI flash
image, u-boot-rockchip-spi.bin.

The i2c locks up when initialized before relocation, and it stays broken
in Linux as well breaking the ability to boot Linux.
The i2c bus and pmic was not actually used in pre-reloc before
commit ad607512f5 ("power: pmic: rk8xx: Support sysreset shutdown method")
The cause is not known.
This is board-specific, other boards that do not add the option to
include the i2c bus in pre-reloc DT are not affected.
