powerpc/85xx: Read board switch settings on p1_p2_rdb
PCA9557 is parallel I/O expansion device on I2C bus which stores various board switch settings like NOR Flash-Bank selection, SD Data width. On board: switch SW5[6] is to select width for eSDHC ON - 4-bit [Enable eSPI] OFF - 8-bit [Disable eSPI] switch SW4[8] is to select NOR Flash Bank for Booting OFF - Primary Bank ON - Secondary Bank Read board switch settings on p1_p2_rdb and configure corresponding eSDHC width.
