ARM: clps711x: Remove EP72XX_ROM_BOOT option
CLPS711X CPUs have 128 bytes of on-chip Boot ROM with an instruction sequence that configure UART1 to receive up to 2 Kbytes of serial data which is then placed in the on-chip SRAM. Once the download is complete, the program counter jumps to SRAM to begin executed the downloaded data. The purpose of this mode is to allow the downloaded code to facilitate programming of FLASH or other ROM device. Selection of the internal Boot ROM is accomplished at power-on-reset time. No reason to keep this special (develop only) mode in the kernel. This patch removes EP72XX_ROM_BOOT kernel symbol.

Say Y here if you intend to run this kernel on the ARM Prospector
720T.

- help
- If you say Y here, your CLPS711x-based kernel will use the bootstrap
- mode memory map instead of the normal memory map.
-
- Processors derived from the Cirrus CLPS711X core support two boot
- modes. Normal mode boots from the external memory device at CS0.
- Bootstrap mode rearranges parts of the memory map, placing an
- internal 128 byte bootstrap ROM at CS0. This option performs the
- address map changes required to support booting in this mode.

- You almost surely want to say N here.
