2007-11-23Blackfin arch: use do_div() for the 64bit division as pointed out by BerndMike Frysinger3-378/+8
If you need a 64 bit divide in the kernel, use asm/div64.h. Revert the addition of udivdi3. Cc: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-11-15Blackfin arch: move the init sections to the end of memory to help decrease ↵Robin Getz3-24/+33
memory fragementation move the init sections to the end of memory, so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob.

2007-10-30Blackfin arch: Fix bug set correct baud for spi mmc and enable SPI after DMA.Sonic Zhang2-4/+4
Changes: 1. The baud for spi mmc defined in board file is not used by the old spi driver. A slower value from spi framework is used instead. In latest bug fixing, the correct baud is use which is too high for spi MMC card. 2. SPI is enabled only after DMA is started. 3. MMC detection IRQ is set to 55.

2007-10-29Blackfin arch: Fix random crash issue found by Michael.Robin Getz1-2/+4
This is fixes a problem where we could jump to the wrong address. By doing a "p0 = reti; jump (p0)". If a different, higher level interrupt came in, just before, rather than returning to the calling function, we would return to a random place in the kernel. This very elegant fix from Bernd grabs the return location off the stack, and places it into P0, so when we do a return, it goes to the correct place.

- move the CONFIG_KGDB into one block, for easier reading - remove printk from printk_address, and pass around buffers. Also print out the labels when decoding CPLB errors, so you know exactly where the error was. - Do not use fixed addresses, becuase people do not know where they come from. - Turn the printing level down on the dump, so if you don't want, only the signal prints out - just like on other archs. If a kernel/interrupt crashes, it should dump everything all the time Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

This fixes two things: - stop calling write_lock_irq/write_unlock_irq which can turn modify irq levels - don't calling mmput when handing exceptions - since this might_sleep, which does a rti, and leaves us in kernel space (irq15, rather than irq5).
