Masahiro Yamada 58dac32764 powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260
Before this commit, CONFIG_MPC8260 and CONFIG_8260
were used mixed-up.

All boards with mpc8260 cpu defined both of them:
  - CONFIG_MPC8260 was defined in board config headers
      and include/common.h
  - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk

We do not need to have both of them.
This commit keeps only CONFIG_MPC8260.

This commit does:
 - Delete CONFIG_8260 and CONFIG_MPC8260 definition
   in config headers and include/common.h
 - Rename CONFIG_8260 to CONFIG_MPC8260
    in arch/powerpc/cpu/mpc8260/config.mk.
 - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260

/*
* hymod configuration data - passed by boot code via the board information
* structure (only U-Boot has support for this at the moment)
*
* there are three types of data passed up from the boot monitor. the first
* (type hymod_eeprom_t) is the eeprom data that was read off both the main
* (or mother) board and the mezzanine board (if any). this data defines how
* many Xilinx fpgas are on each board, and their types (among other things).
* the second type of data (type xlx_mmap_t, one per Xilinx fpga) defines where
* in the physical address space the various Xilinx fpga access regions have
* been mapped by the boot rom. the third type of data (type xlx_iopins_t,
* one per Xilinx fpga) defines which io port pins are connected to the various
* signals required to program a Xilinx fpga.
*
* A ram/flash "bank" refers to memory controlled by the same chip select.
*
* the eeprom contents are defined as in technical note #2 - basically,
* a header, zero or more records in no particular order, and a 32 bit crc
* a record is 1 or more type bytes, a length byte and "length" bytes.
