| |
| ** 02/02/16 ********************************************************** |

| * rewrote flash chip probing |
| * always use ioremap now |
| * flash chips above 128k should work transparent |
| * Support for newer VIA chipsets |
| |
| ** 00/10/15 * 0.3.0pre1 ********************************************** |
| |
| * added patch from Eric Estabrook |
| * support for 256k flash chips on intel 430/440 chipsets and via vp3 |
| * split up source into several files |
| * Changes for Ruffian AXP machines. Does not work (yet). |
| |
| ** 99/07/29 * 0.2.101 ************************************************ |
| |
| * Oh well.. 11 months? Impossible. I am a lazy guy. Implemented |
| some support for VIA Apollo VP3. Don't know whether it works, since |
| I don't have one. |
| |
| ** 98/09/06 ********************************************************** |
| |
| patches by prumpf@jcsbs.lanobis.de: |
| * The pointer to bios_release in bios.c was on the flush pointer's |
| position. This caused Oopses. |
| * When bios_read was called with a file position after the actual end |
| of bios, it tried to read non-existant memory positions due to size |
| being unsigned (it isn't anymore) , causing spontaneous reboots on |
| my system |
| |
| ** 98/08/22 ********************************************************** |
| |
| * Well,.. The diskless spectacle (0.2.100) was caused by a little bug |
| in in handling Intel PCI chipsets. Works now. |
| * Threw out the chipset_backout stuff. the PCI chipset handling should |
| always leave the machine in the same state it was before. ALWAYS. |
| |
| ** 98/08/18 * 0.2.100 ************************************************ |
| |
| * Threw out the mem_type stuff. There are more important things than |
| this. |
| * Argh! After flashing fine on an Intel 28F001BT, the computer kept |
| hanging in an endless loop and refused writing the emergency boot |
| block to the end :-( There's some work until 0.3 is ready. |
| Implemented a timeout so that the system will not hang forever if |
| the flashchip behaves unexpected. |
| * Removed x86 probing in a loop. I think it never found anything else |
| but the system bios and *maybe* the graphics adapter bios. On the |
| other hand, it reconfigures some networking cards to silence. |
| Bad thing on diskless Linux boxes :) |
| |
| ** 98/08/15 ********************************************************** |
| |
| * added some changes for intel to compile without warnings.. |
| |
| ** 98/08/02 ********************************************************** |
| |
| * What a boring job! Checked some dozen of flash chip entries today |
| and added a lot of new ones. I bet it gets hard to find anything |
| this driver does not know. |
| |
| ** 98/07/28 ********************************************************** |
| |
| * Yeah! Atmel Chips finally work.. These Atmel guys are really weird. |
| * Testing last instead of first written byte now, when polling for the |
| end of a write access. |
| |
| ** 98/07/28 ********************************************************** |
| |
| * Well, I am definitely spending too much time in IRC, but detecting |
| PCI cards' bioses works now (at least for me) |
| * Thrown out some obsolete stuff. |
| * Declared PCI and Flash reading/writing __inline__. Don't know, |
| whether this is a good idea. But let's try it for a while. |
| * Aaaargh! Some major mistakes in handling whether a flash has to |
| be erased before programming. FIXED! |
| * Even worse. An endless loop made it into writing in 0.2.99. Sorry! |
| I had no chance to test writing on an intel board with that release. |
| At least my warning, not to write, made sense. |
| * Intel flashchips are supported now!! It's at least tested on my |
| Alpha AXP LX164 Board (1MByte i28f008 chip) But all Intel flash chips |
| seem to work in the same way. |
| * Atmel 64kByte flash chips supported. |
| |
| ** 98/07/27 ********************************************************** |
| |
| * Split up flash_probe in 2 parts to be able to expand probing on |
| PCI bioses and others correctly. |
| * Turned around 1st and 2nd probing codes. This is funny, Atmel |
| Flashroms give some wrong numbers if they are probed with the |
| 0x80/0x60 way. I only hope that no flashchips react on the |
| 0x90 method with wrong values. |
| |
| ** 98/07/19 * V0.2.99 ************************************************ |
| |
| * Reading the flashchip works now on Alpha AXP (at least on my LX164 |
| Board) |
| Writing ought to work, too, but Intel Flashchips are not supported |
| yet. This should be done until 0.3.0. |
| NOTE: I have no idea whether this driver still works on intel |
| boards or not. There have been too many changes. Please try, but |
| do not flash with this release of the driver. |
| * Minor Changes and fixes. Naming scheme changed a bit. This version |
| might work on James Mastros' machine again ?!? |
| |
| ** 98/07/11 ********************************************************** |
| |
| * Started porting stuff to Alpha AXP architecture to continue testing |
| the flashing routines. We have a lot of tests next week, so I |
| won't get much stuff done.. |
| Porting to AXP seems to be much more work than I thought. It may |
| take some time until the next version is released. |
| * Moved major number again. This time we have an official major |
| number for /dev/bios. Thanks to Hans Peter Anvin. |
| (Well, we have this one since May 1st, sorry for the delay) |
| |
| ** 98/06/26 * V0.2.95 ************************************************ |
| |
| * added all Manufacturer IDs from the JEDEC standards publication. |
| * sorry for not having released a new version since months, but |
| my x86 machine died and I have no chance to do any testing right |
| now. I guess I must get a new Intel box, as Alpha AXP are all |
| delivered with the same Intel flash chips. |
| |
| ** 98/04/30 * V0.2.9 ************************************************* |
| |
| * removed ioctls. They have been really unneccesary and did not fit |
| into the new driver layout. |
| * cleaned up the code. Hey, it should be readable again. |
| * Moved device minors from 10+ to 0+ |
| * Rewrote most of the documentation |
| * changed intel shadowing routines. Now original values are saved |
| and shadowing is turned off for 0xc0000 to 0xdffff, too (This |
| was needed to support 2MBit system bios flash chips. Thanks again |
| to Matthew Harrell for intensive testing. |
| * Removed dirty hacks from bios_read_proc() |
| * Added some fields to struct flashdevice to support all ROM types, |
| not only flash roms. Probing for other types still missing. |
| * Implemented probing for some strange Winbond chips (0x80/0x20). |
| |
| ** 98/04/27 * V0.2.8 ************************************************* |
| |
| *** Attention *** This version has a lot of changes since |
| 0.2.7, so be very careful, when testing. Things may |
| be broken that used to work. |
| |
| * Rewrote big parts of the driver to (theoretically) support |
| multiple flash chips and/or ROM areas. |
| * Tried to implement support for 2MBit System BIOS chips, but |
| I have no idea, whether it works. I don't have one. |
| * added some more OPTi, SiS and VIA PCI chipsets to chipset list. |
| They have no function yet, though. |
| * Some weird computers have an ISA bridge, but don't have it declared |
| as one. Now probing for known ISA bridge IDs. (Thanks to Matthew |
| Harrell for reporting this.) |
| * Added some new flashchip IDs and made some old ones work. |
| |
| ** 98/04/24 * V0.2.7 ************************************************* |
| |
| * rewrote shadowing and wp functions to use a pci_functions structure |
| This makes it very easy to include new PCI chipsets. |
| * function chipset_init() detects PCI chipset. |
| * modversions support. Thanks to Matthew Harrell. |
| * moved PCI bridge detection to chipset_init() |
| |
| ** 98/04/23 * V0.2.6 ************************************************* |
| |
| * repaired flashchip_ready_toggle and flashchip_ready_poll. |
| * Set WRITE_DELAY to 300 as it should be (works now) |
| * NOTE: These two changes make the operation of /dev/bios |
| theoretically correct, and by that quite secure. |
| |
