The 6x_upgrade script is used to upgrade U-Boot in SPI-NOR on Nitrogen6x/SABRE Lite boards using U-Boot's 'sf' command. U-Boot is placed at offset 0x400 in flash, and the script currently only erases 0x50000 bytes. Since the current head is 319k, any additional features enabled in the configuration will exceed the space erased and cause errors re-programming the device. This patch increases the erase size to the full size of the region allocated for the U-Boot binary.
