PS1: 
Seems good, only minor things.
Can you split the patch into three to have one for each new flashchip. Also adding a link to the corresponding datasheets in the commit message.

File flashchips.c:

PS1, Line 9671: {
              : 				.eraseblocks = { {2 * 1024 * 1024, 1} },
              : 				.block_erase = SPI_BLOCK_ERASE_60,
              : 			}
The chip erase can also be performed with `SPI_BLOCK_ERASE_C7`
