* dediprog: Fix small, unaligned readsNico Huber2018-12-061-4/+4
| | | | | | | | | | | | | | | This never was a use case until now but the `--fmap` code makes it obvious: Unaligned reads that were smaller than the `chunksize` here, were extended without considering the length of the buffer read into. With that fixed we run into the next problem: dediprog_spi_bulk_read() shouldn't report an error when an empty read is unaligned.

* Add support to get layout from fmap (e.g. coreboot rom)Arthur Heymans2018-10-237-10/+648
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.

* chipset_enable.c: Mark Intel HM55 as DEPAngel Pons2018-08-221-1/+1
| | | | | | | | | | | | | Tested reading, writing and erasing the internal flash chip using an HP 630 laptop with an Intel HM55. However, since all ME-enabled chipsets are marked as DEP instead of OK, this one shall follow suit as well.

| | | | | | | | | | | | | | | | Copy 'n paste support for Macronix MX25U51245G. 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).

* programmer: Add Developerbox/CP2104 bit bang driverDaniel Thompson2018-08-174-2/+278
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* bitbang_spi: Add half-duplex optimizationsDaniel Thompson2018-08-171-5/+19
| | | | | | | | | | | | | | | | | | 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.
