* 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.

| | | | | | | | | | | | | | | | | | | | On systems where the overhead of getting/setting pins is much greater than the half period (for example, USB bit banging) it significantly boosts performance if we can bang more than one bit at the same time.

| | | | | | | | | | | | | | | | | | This checks that the MTD sysfs node we will use actually exists prior to calling setup code. Although the setup code will eventually catch such an error, we need to think about the use case before printing a possibly irrelevant/confusing error message to the terminal. This patch makes it so that we only print an error message if the user specifies a non-existent MTD device. Otherwise, the failure is considered benign and we only print a debug message prior to bailing out.

But practical concerns (i.e., bugs) have meant we don't quite do this. For reads: Bug https://b/35573113 shows that some SPI-based MTD drivers don't yet handle very large transactions. 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. And it's not actually used in this driver now. If we could figure out what we really want to use it for, then we could try to set it appropriately.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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].

* dediprog: implement command spec for firmware >= 7.2.30David Hendricks2018-03-281-18/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the latest command spec for Dediprog SF100/SF600 programmers. Since we now have more than two protocols to deal with the is_new_prot() function is replaced with protocol() which returns an enum specifying which protocol is supported. The latest spec (FW >= 7.2.30) updates read and write packets. It's been tested on an SF600 using firmware 7.2.21 and SF600Plus using FW 7.2.30. The latest command protocol has a few small but important changes: - Read packets have two more bytes: 11: B4Addr: address len (3 or 4) 12: Dummy cycle /2 - Write packets have four more bytes: 11, 12: 16 HSBs of page size 13, 14: 16 LSBs of page size (The spec seems to be mistaken, though, as 11 and 12 are actually LSBs instead of HSBs) Change-Id: I1a53c143948ec40d40433621891a2871d8815f2f Signed-off-by: David Hendricks <dhendricks@fb.com> Reviewed-on: https://review.coreboot.org/23836 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>

* Fix compilation with older MinGW versionsAntonio Ospite2018-03-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | The __MINGW_PRINTF_FORMAT constant has been defined back in 2012 https://sourceforge.net/p/mingw-w64/mingw-w64/ci/77bc5d6103b5fb9f59fbddab1583e69549913312/ However older toolchains are still around and some user reported the following compilation failure: flash.h:336:1: error: '__MINGW_PRINTF_FORMAT' is an unrecognized format function  type [-Werror=format=]  __attribute__((format(__MINGW_PRINTF_FORMAT, 2, 3))); Fix this by defining the constant when it isn't already; the change does not affect other compilers because it's guarded by "#ifdef __MINGW32__". Setting __MINGW_PRINTF_FORMAT to gnu_printf is exactly what newer MinGW versions do when __USE_MINGW_ANSI_STDIO is defined, which it is in flashrom Makefile.

Also, when the install script was written, git- rev-parse had a bug when it wasn't run from the root directory. They fixed the behaviour by now. To simplify things and not have to account for that too, we just bail out when the script is run from a sub- directory.
