* Move erase verification to generic codeCarl-Daniel Hailfinger2011-06-261-24/+6
| | | | | | | | | | | | Erase functions are no longer called from chip drivers and thus their internal erase verification can be moved to generic code. This also makes it easier to skip the verify step if desired and to differentiate between failed command submission and failed erase verification. Corresponding to flashrom svn r1353.

* Tiny fix for a small fixStefan Tauner2011-05-281-3/+1
| | | | | | | | | | | | | There was one line break added too much in the previous commit, sorry. the probing functions need to output at least one '\n' for satisfactory output. that means even in error cases they have to do that. OTOH they should not output a sequence of "\n\n" because it would distort the verbose probing output with empty lines. Corresponding to flashrom svn r1322.

* Refine status register and lock printing of Atmel and AMIC SPI chipsCarl-Daniel Hailfinger2011-05-191-258/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add lock printing for AMIC A25L05PT, A25L05PU, A25L10PT, A25L10PU, A25L20PT, A25L20PU, A25L40PT, A25L40PU, A25L80P, A25L16PT, A25L16PU, A25L512, A25L010, A25L020, A25L040, A25L080, A25L016, A25L032, A25LQ032 to a25.c. Add lock printing for Atmel AT26DF081A, AT26DF161, AT26DF161A, AT26DF321. Move Atmel AT25*/AT26* lock related functions originally added in r1115 from spi25.c to at25.c. For SPI chips the lock printing was handled by one common function, but sharing a common function which only is a big switch() statement doesn't make sense, especially if we can define lock printing functions per flash chip anyway. The printlock function pointer in struct flashchip is used to print status register and locking information, and serves as replacement for implicit status register and lock printing during probe. That code will later be changed to store locking info in a machine- accessible data structure so flashrom can handle locked regions correctly. Corresponding to flashrom svn r1316.

* Kill central list of SPI programmersMichael Karcher2011-05-111-2/+2
| | | | | | | | | | | | | | | | | | Remove the array spi_programmer, replace it by dynamic registration instead. Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").

* Convince compilers to put constant data into the .rodata sectionMathias Krause2011-01-171-9/+9
| | | | | | | | | | | | | | | | This patch reduces the stack usage by declaring 'const' stack variables as 'static const' so they end up in the .rodata section instead of being copied from there to the stack for every invocation of the corresponding function. As a plus we end up in having a smaller binary as the "copy from .rodata to stack" code isn't emitted by the compiler any more (roughly -100 bytes). Corresponding to flashrom svn r1252.

* Fix internal offset calculations for SPI BYTE PROGRAM and SPI AAI PROGRAMCarl-Daniel Hailfinger2010-10-271-4/+12
| | | | | | | | | | | | | | | | The bug was invisible so far because we always started at offset 0. The pending partial write patch uses nonzero start offsets and trips over this bug. Clarify a few comments in IT87 SPI. Thanks to Idwer Vollering for reporting write breakage with my latest partial write patch. This should fix the underlying problem.

* Move implicit erase out of chip driversCarl-Daniel Hailfinger2010-10-081-16/+0
| | | | | | | | | | | | | | | | | | Flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, and kill some dead erase functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written. Corresponding to flashrom svn r1206.

Thanks to David Daney for compile testing on MIPS (big endian). Thanks to Uwe Hermann for compile and runtime testing on x86_64. DO NOT RUN flashrom ON NON-X86 AFTER APPLYING THIS PATCH!
