In “Table 1-2 16 M Flash Boot Address Allocation”
Offset Length Description 0x600000 0x1000000 Reseved
0x600000 0x0A00000 Reserved
Because 0x6+0x0A=0x10=16 (16MiB of Flash)
Where as 0x6+0x10=0x16=22 (22MiB of Flash)
The Starfive VisionFive 2 has a 16MiB NOR flash, while the reserved-data partition is declared starting at address 0x600000 with a size of 0x1000000. This causes the kernel to output the following warning: [ 22.156589] mtd: partition "reserved-data" extends beyond the end of device "13010000.spi.0" -- size truncated to 0xa00000 It seems to be a confusion between the size of the partition and the end address. Fix that by specifying the right size.
