From af835ce5169cc7829928e8e224508526b9ef2870 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 18 Oct 2008 21:43:30 +0000 Subject: change the way ./files* and the generic kernel files are applied. ./files now applies to *ALL* kernel versions, and is copied along with ./files-* - this gets rid of quite a bit of redundancy in the extra kernel drivers. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@13010 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../files-2.6.23/arch/mips/bcm947xx/Makefile | 7 + .../files-2.6.23/arch/mips/bcm947xx/cfe_env.c | 229 +++++++++ .../arch/mips/bcm947xx/include/nvram.h | 37 ++ .../brcm47xx/files-2.6.23/arch/mips/bcm947xx/irq.c | 86 ++++ .../files-2.6.23/arch/mips/bcm947xx/nvram.c | 125 +++++ .../files-2.6.23/arch/mips/bcm947xx/prom.c | 61 +++ .../files-2.6.23/arch/mips/bcm947xx/setup.c | 246 ++++++++++ .../files-2.6.23/arch/mips/bcm947xx/time.c | 62 +++ .../brcm47xx/files-2.6.23/arch/mips/cfe/Makefile | 5 + .../brcm47xx/files-2.6.23/arch/mips/cfe/cfe.c | 533 +++++++++++++++++++++ .../files-2.6.23/arch/mips/cfe/cfe_private.h | 176 +++++++ .../files-2.6.23/drivers/mtd/maps/bcm47xx-flash.c | 439 +++++++++++++++++ .../brcm47xx/files-2.6.23/include/asm-mips/cfe.h | 189 ++++++++ .../include/asm-mips/mach-bcm947xx/gpio.h | 67 +++ .../asm-mips/mach-bcm947xx/kernel-entry-init.h | 26 + .../brcm47xx/files/arch/mips/bcm947xx/Makefile | 7 -
