Patch set updated for serialice: d51fc6f Reorganize code to support "high speed" serial transfers
by Patrick Georgi 03 Dec '11

03 Dec '11

Patrick Georgi (patrick(a)georgi-clan.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/460 -gerrit commit d51fc6feb10e755ad2b9d38502b3088d6167f240 Author: Patrick Georgi <patrick.georgi(a)secunet.com> Date: Thu Dec 1 12:09:56 2011 +0100 Reorganize code to support "high speed" serial transfers This requires some chipset specific handling in case transfers faster than 115200bps are used. Due to that, the build must be reorganized a bit. This change doesn't actually add high speed support code, but does the reorganization only. As an example, Kontron 986LCD-M was converted to "new-style": southbridge code now resides in southbridge/intel-ich7.c, superio code in superio/winbond-w83627thg.c, both pointed at using Kconfig. Other boards using this southbridge or superio can reuse the files, reducing duplication.

New patch to review for serialice: 9536981 Add hooking mechanism to provide for special parsers
by Patrick Georgi 01 Dec '11

01 Dec '11

Patrick Georgi (patrick(a)georgi-clan.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/462 -gerrit commit 953698142a9a0ac17af089b89d82b03cac409262 Author: Patrick Georgi <patrick.georgi(a)secunet.com> Date: Thu Dec 1 13:03:30 2011 +0100 Add hooking mechanism to provide for special parsers Right now the code hardcodes a lot of special handling. The idea is to move these into functions that are run until one is successful, or use a standard routine if none claimed responsibility. Later-on, these handlers could be chipset specific and enabled automatically to provide a better view of what's going on.
