This is a general announcement of some work being done to update XXS1500 support to a 2.6 kernel level. Testers welcome. This isn't ready for CVS inclusion yet, still needs more testing and validation, but to stop the hordes of people emailing me about it (Hi Marcel), here it is being publicly announced: http://dev.gentoo.org/~robbat2/xxs1500/linux-xxs1500-20040927.patch-dangerous.gz Applies against latest CVS. Contains: - Kconfig stuff for the BCM5222 Dual PHY. - XXS1500 PCI IRQ stuff - MTD access to the onboard flash (Pete's code) - Kconfig stuff for MTD flash - drivers/pcmcia/au1000_generic.c: cleanup debug code - drivers/pcmcia/au1000_xxs1500.c: port to 2.6 - Move include/asm-mips/xxs1500.h to include/asm-mips/mach-xxs1500/xxs1500.h No warranty on it, I don't trust my PCMCIA code entirely yet. From the original codebase: a) au_writel((au_readl(GPIO2_PINSTATE) & ~(1<<14))|(1<<30), GPIO2_OUTPUT); b) au_writel((au_readl(GPIO2_PINSTATE) | (1<<14))|(1<<30), GPIO2_OUTPUT); The 1<<14 indicates a specific location to set, and the 1<<30 says to enable output on that location. In arch/mips/au1000/xxs1500/board_setup.c, snippet a is commented as 'turn off power'. In drivers/pcmcia/au1000_xxs1500.c, snippet a is commented as 'turn on power', and snippet b is commented as 'turn off power'. Your guess is as good as mine as to which does what. I've replaced them with two macros: XXS1500_GPIO2_PCMCIA_POWER_ON XXS1500_GPIO2_PCMCIA_POWER_OFF Due to the number of times they occur. -- Robin Hugh Johnson E-Mail : robbat2@xxxxxxxxxx Home Page : http://www.orbis-terrarum.net/?l=people.robbat2 GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
