Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usage 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>
