New Revision: 4350
Added:
trunk/coreboot-v2/src/mainboard/via/epia-m700/driving_clk_phase_data.c
Removed:
trunk/coreboot-v2/src/mainboard/via/epia-m700/DrivingClkPhaseData.c
Modified:
trunk/coreboot-v2/src/mainboard/via/epia-m700/Options.lb
trunk/coreboot-v2/src/mainboard/via/epia-m700/cache_as_ram_auto.c
trunk/coreboot-v2/src/mainboard/via/epia-m700/fadt.c
trunk/coreboot-v2/src/mainboard/via/epia-m700/get_dsdt
trunk/coreboot-v2/src/mainboard/via/epia-m700/irq_tables.c
trunk/coreboot-v2/src/mainboard/via/epia-m700/wakeup.c
Log:
A bunch of additional EPIA-M700 cleanups and also some non-cosmetic changes:
- Make get_dsdt script executable.
- Rename DrivingClkPhaseData.c to driving_clk_phase_data.c.
- Set proper IRQ_SLOT_COUNT value in the hope that the '14' from irq_table.c
is correct.
- Fix broken or incorrect #include names to increase likelyhood of a
successful compile.
