Add gpio_request() into zylonite. To simplify the code, error checking is omitted since this is being performed early.

2009-04-27[ARM] pxa/zylonite: fix the issue of unused SDATA_IN_1 pin get AC97 not workingEric Miao
GPIO17_SDATA_IN_1 and GPIO36_SDATA_IN_1 are originally designed for the 2nd codec but unused on the board, yet they are initialized incorrectly by the bootloader as the SDATA_IN_1 alternate function, thus causing AC97 fail to work. Fix this issue by configuring these pins as normal GPIO to avoid the noise from these pins being treated as signals from the 2nd codec. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usageEric Miao
Considering the header mess ATM, it is not always possible to include the correct header files within board code. Let's keep this simple: <mach/pxa25x.h> - for pxa25x based platforms <mach/pxa27x.h> - for pxa27x based platforms <mach/pxa300.h> - for pxa300 based platforms <mach/pxa320.h> - for pxa320 based platforms <mach/pxa930.h> - for pxa930 based platforms NOTE: 1. one header one board file, they are not compatible (i.e. they have conflicting definitions which won't compile if included together). 2. Unless strictly necessary, the following header files are considered to be SoC files use _only_, and is not recommended to be included in board code: <mach/hardware.h> <mach/pxa-regs.h> <mach/pxa2xx-regs.h> <mach/pxa3xx-regs.h> <mach/mfp.h> <mach/mfp-pxa2xx.h> <mach/mfp-pxa25x.h> <mach/mfp-pxa27x.h> <mach/mfp-pxa3xx.h> <mach/mfp-pxa300.h> <mach/mfp-pxa320.h> <mach/mfp-pxa930.h> Signed-off-by: Eric Miao <eric.miao@marvell.com>
