powerpc: remove genietv board support
Enough time has passed since this board was moved to Orphan. Remove. - Remove board/genietv/* - Remove include/configs/GENIETV.h - Clean-up if defined(CONFIG_GENIETV) - Move the entry from boards.cfg to doc/README.scrapyard Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

- * genietv/genietv.c
- *
- * The GENIETV is using the following physical memorymap (copied from
- * the FADS configuration):
- *
- * ff020000 -> ff02ffff : pcmcia
- * ff010000 -> ff01ffff : BCSR connected to CS1, setup by 8xxROM
- * ff000000 -> ff00ffff : IMAP internal in the cpu
- * 02800000 -> 0287ffff : flash connected to CS0
- * 00000000 -> nnnnnnnn : sdram setup by U-Boot
- *
- * CS pins are connected as follows:
- *
- * CS0 -512Kb boot flash
- * CS1 - SDRAM #1
- * CS2 - SDRAM #2
- * CS3 - Flash #1
- * CS4 - Flash #2
- * CS5 - LON (if present)
- * CS6 - PCMCIA #1
- * CS7 - PCMCIA #2
- *
- * Ports are configured as follows:
- *
- * PA7 - SDRAM banks enable
