2007-02-17[POWERPC] QE: clean up ucc_slow.c and ucc_fast.cTimur Tabi1-4/+4
Refactored and cleaned up ucc_fast.c and ucc_slow.c so that the two files look more alike and are easier to read. Removed uccf_printk() and related functions, because they were just front-ends to printk(). Fixed some spacing and tabbing issues. Minor optimizations of some code. Changed the type of some variables to their proper type (mostly buffer descriptors). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-02-17[POWERPC] add of_get_mac_address and update fsl_soc.c to use itTimur Tabi1-0/+2
Add function of_get_mac_address(), which obtains the best MAC address to use from the device tree by checking various properties in order. The order is: 'mac-address', then 'local-mac-address', then 'address'. It skips properties that contain invalid MAC addresses, which were probably not initialized by U-Boot. Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call of_get_mac_address(). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-02-16[POWERPC] More DCR native fixupsDavid Gibson1-2/+2
Getting BenH's new EMAC driver working on 440GP, I found some more problems in the native mode paths of the new DCR code: - dcr_map() is supposed to return a dcr_host_t, but the native version is a macro that doesn't expand to an expression. With native DCRs, dcr_host_t is an empty structure, so we just use a constructor expression instead. - dcr_unmap() uses {} instead of the safer do {} while (0) idiom to implement a no-op Here's a fix.

2007-02-14[POWERPC] Use udbg_early_init() on ppc32David Gibson1-0/+1
udbg_early_init() is a function used on 64 bit systems, which initializes whichever early udbg backend is configured. This function is not called on 32-bit, however if btext early debug is enabled it does have an explicit, inline, #ifdef-ed assignment performing analagous initialization. This patch makes things more uniform by folding the btext initialization as an option into udbg_early_init() and calling that from the 32-bit setup path.

2007-02-13[POWERPC] cell: PPU Oprofile cleanup patchCarl Love1-9/+6
This is a clean up patch that includes the following changes: -Some comments were added to clarify the code based on feedback from the community. -The write_pm_cntrl() and set_count_mode() were passed a structure element from a global variable. The argument was removed so the functions now just operate on the global directly. -The set_pm_event() function call in the cell_virtual_cntr() routine was moved to a for-loop before the for_each_cpu loop Signed-off-by: Carl Love <carll@us.ibm.com> Signed-off-by: Maynard Johnson <mpjohn@us.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

2007-02-13[POWERPC] Fix vDSO page count calculationBenjamin Herrenschmidt1-5/+0
The recent vDSO consolidation patches broke powerpc due to a mistake in the definition of MAXPAGES constants. This fixes it by moving to a dynamically allocated array of pages instead as I don't like much hard coded size limits. Also move the vdso initialisation to an initcall since it doesn't really need to be done -that- early. Applogies for not catching the breakage earlier, Roland _did_ CC me on his patches a while ago, I got busy with other things and forgot to test them.

2007-02-13[POWERPC] Virtual DMA support for floppy driver for new powerpc architecturePavel Fedin1-13/+122
During ppc64+ppc merge virtual DMA code for floppy driver was not ported. This patch restores virtual DMA support for floppy in new powerpc target. It is necessary at least on Pegasos and AmigaOne machines for the floppy drive to function. ISA DMA controller works incorrectly there due to its addressing limitations. Virtual DMA mode is activated by floppy=nodma option passed to the kernel (or module). There's no automatic switch like on i386.

Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.

2007-02-11[PATCH] consolidate line discipline number definitionsTilman Schmidt1-18/+0
The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.
