I think that is copy-paste error in documentation.
In the same TRM, you 'll find the correct address offsets for GPMC Registers in
below
*Section: 15.4.7.1 GPMC Register Summary*
Register Starting Offset
End Offset
GPMC_BCH_RESULT4_i 0x0000 0300 + (0x0000 0010 * i) 0x5000 0300 + (0x0000
0010 * i)
GPMC_BCH_RESULT5_i 0x0000 0304 + (0x0000 0010 * i) 0x5000 0304 + (0x0000
0010 * i)
GPMC_BCH_RESULT6_i 0x0000 0308 + (0x0000 0010 * i) 0x5000 0308 + (0x0000
0010 * i)
Where i = 0 to 7 ..
So that makes last address 0x5000_0378 (for GPMC_BCH_RESULT6_7)
As the each register bank (i) is incrementing at 0x10, so last accessible
address is 0x37F.
I have already raised documentation bug for AM335x TRM,
Need to raise the same for DRA7xx TRM.

Yes, that is correct. I have fixed that now.
