1035 * For now this code is only used on x86.
1036 *
1037 * init_sequence_f_r is the list of init functions which are run when
1038 * U-Boot is executing from Flash with a semi-limited 'C' environment.
1039 * The following limitations must be considered when implementing an
1040 * '_f_r' function:
1041 * - 'static' variables are read-only
1042 * - Global Data (gd->xxx) is read/write
1043 *
1044 * The '_f_r' sequence must, as a minimum, copy U-Boot to RAM (if
1045 * supported). It _should_, if possible, copy global data to RAM and
1046 * initialise the CPU caches (to speed up the relocation process)
1047 *
1048 * NOTE: At present only x86 uses this route, but it is intended that
1049 * all archs will move to this when generic relocation is implemented.
