flashchips: Add SST26VF016B(A), SST26VF032B(A), SST26VF064B(A)
This patch seems to have originally been from
https://patchwork.coreboot.org/patch/4126/ . The most recent version
seems to be in OpenEmbedded (commit 503a572) which added support for
16Mbit and 32Mbit variants.
The OpenEmbedded patch also makes changes to linux_spi.c to add some
debug prints which are omitted in this version.
From the original commit message:
Differences between SST26 and SST25:
1. The WREN instruction must be executed prior to WRSR [Section 5.31].
There is no EWSR.
2. Block protection bits are no longer in the status register. There
is a dedicated 144-bit register [Table 5-6]. The device is
write-protected by default. A Global Block-Protection Unlock
command unlocks the entire memory [Section 4.1].
