Change in flashrom[master]: bitbang_spi: Add half-duplex optimizations

by Daniel Thompson (Code Review)

Hello Paul Menzel, build bot (Jenkins), Nico Huber, Patrick Georgi, I'd like you to reexamine a change. Please visit https://review.coreboot.org/26947 to look at the new patch set (#3). Change subject: bitbang_spi: Add half-duplex optimizations ...................................................................... bitbang_spi: Add half-duplex optimizations Currently, the core of bitbang_spi is a full-duplex SPI loop but in practice this code is only ever used half-duplex. Spliting this code into two half duplex loops allows us to optimize performance by reducing communications and/or CPU pipeline stalls. The speed up varies depending on how much the overhead of getting/setting pins dominates execution time. For a USB bit bang driver running on a 7th generation Core i5, the time to probe drops from ~7.7 seconds to ~6.7 seconds when this patch is applied.

Change in flashrom[master]: programmer: Add Developerbox/CP2104 bit bang driver

by Daniel Thompson (Code Review)

Hello Paul Menzel, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/26948 to look at the new patch set (#3). Change subject: programmer: Add Developerbox/CP2104 bit bang driver ...................................................................... programmer: Add Developerbox/CP2104 bit bang driver The 96Boards Developerbox (a.k.a. Synquacer E-series) provides a CP2102 debug UART with its GPIO pins hooked up to the SPI NOR FLASH. The circuit is intended to provide emergency recovery functions without requiring any additional tools (such as a JTAG or SPI programmer). This was expected to be very slow (and it is) but CP2102 is much cheaper than a full dual channel USB comms chip. Read performance is roughly on par with a 2400 baud modem (between 60 and 70 minutes per megabyte if you prefer) and write performance is 50% slower still. The full recovery process, with backup and verification of 4MB data written takes between 14 and 15 hours. Thus it is only really practical as an emergency recovery tool, firmware developers will need to use an alternative programmer.

I don't pretend to know a whole lot about SPI FLASH so its mostly copied from other MX25U devices and double checked a few bits and pieces against the datasheet. I have tested basic probe, read, erase and write using layout files. I tested both with 4MB@0x0000000 and 64K0@0x3f00000 (the later means I have tested 4-byte addressing).
