powerpc/5121: add initial support for PDM360NG board
Adds IFM PDM360NG device tree and platform code. Currently following is supported: - Spansion S29GL512P 256 MB NOR flash - ST Micro NAND 1 GiB flash - DIU, please use "fbcon=map:5 video=fslfb:800x480-32@60" at the kernel command line to enable PrimeView PM070WL3 Display support. - FEC - I2C - RTC, EEPROM - MSCAN - PSC UART, please pass "console=tty0 console=ttyPSC5,115200" on the kernel command line. - SPI, ADS7845 Touchscreen - USB0/1 Host - USB0 OTG Host/Device - VIU, Overlay/Capture support Signed-off-by: Markus Fischer <markus.fischer.ec@ifm.com> Signed-off-by: Wolfgang Grandegger <wg@denx.de> Signed-off-by: Michael Weiss <michael.weiss@ifm.com> Signed-off-by: Detlev Zundel <dzu@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
