We are not able to access the local bus interface in P1022 . Following are the configuration settings:-
PMUXCR[eLBC_DIU] = 10 16-bit GPCM/ 28-bit Address
cfg_rom_loc[0:3] = 0110 On-chip boot ROM-SPI configuration
BR0 : E8001001
OR0 : F80000FF7
BR1 : FF800001
OR1 : FFFF8FF7
BR2 : FFDF0801
Attached is the memory map as per our understanding.
1. While trying to access any register within the specified range as per the base register and option register setting corresponding chip select signal is not asserted.
2. Processor does not boot up if we reconfigure the BR0 and OR0 register values in uboot file.
