Change in flashrom[master]: flashchips: Add SST26VF016B(A), SST26VF032B(A), SST26VF064B(A)

Hello Stefan Tauner, build bot (Jenkins), Nico Huber, I'd like you to reexamine a change. Please visit https://review.coreboot.org/25962 to look at the new patch set (#2). Change subject: flashchips: Add SST26VF016B(A), SST26VF032B(A), SST26VF064B(A) ...................................................................... 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].

So we artificially limit this to block-sized chunks. For writes: It's not clear there is a hard limit. Some drivers will already split large writes into smaller chunks automatically. Others don't do any splitting. At any rate, using *small* chunks can actually be a problem for some devices (b:35104688), as they get worse performance (doing an internal read/modify/write). This could be fixed in other ways by advertizing their true "write chunk size" to user space somehow, but this isn't so easy. As a simpler fix, we can just increase the loop increment to match the read loop. Per David, the original implementation (looping over page chunks) was just being paranoid. So this patch: * clarifies comments in linux_mtd_read(), to note that the chunking is somewhat of a hack that ideally can be fixed (with bug reference) * simplifies the linux_mtd_write() looping to match the structure in linux_mtd_read(), including dropping several unnecessary seeks, and correcting the error messages (they referred to "reads" and had the wrong parameters) * change linux_mtd_write() to align its chunks to eraseblocks, not page sizes Note that the "->page_size" parameter is still somewhat ill-defined, and only set by the upper layers for "opaque" flash.
