Boot procedure flow for a Rockchip rk3066 SoC:
1.Read 2K SDRAM initialization image code to internal SRAM 2.Run image code to do SDRAM initialization 3.Transfer boot image code to SDRAM 4.Run boot image code
Supported system boot from the following devices: Nand Flash SPI nor Flash eMMC device UART interface
If all boot options fail then enter into BootROM mode on the USB OTG port. Unlike later SoC models the rk3066 BootROM doesn't have SDMMC support.
The size of a full U-boot binary is too large for the internal SDRAM memory. Of that 64k size only 32kb sram - 2kb bootrom is available for the first stage.
Similar to the already supported rk3188, the BootROM will attempt to load up the first stage image 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 offset 0x804 after a 4 ASCII character "RK30" header.
With CONFIG_TPL_ROCKCHIP_EARLYRETURN_TO_BROM=y this first stage is combined with the U-boot TPL binary (u-boot-tpl.bin).
For rk3066 with NAND flash and U-boot this gives the following stages:
- TPL: init external SDRAM
- SPL: init SDMMC and read U-boot from SD CARD.
- U-boot: read Linux kernel from SD CARD.
- Kernel
Additionally the rk3066 requires everything the BootROM loads to be RC4-encrypted.

Boot solution with full U-boot stored on SD CARD:
Compile commands(U-boot):
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make mk808_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make menuconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make all
===
Size of SPL and TPL must be aligned to 2kb. If bricked and no BootROM mode shows up then connect pin 8 and 9 of the NAND flash with a needle while reconnecting to the USB OTG port to a PC.
