avr32: Add simple paging support

2010-09-03T13:13:02Z

Use the MMU hardware to set up 1:1 mappings between physical and virtual addresses. This allows us to bypass the cache when accessing the flash without having to do any physical-to-virtual address mapping in the CFI driver. The virtual memory mappings are defined at compile time through a sorted array of virtual memory range objects. When a TLB miss exception happens, the exception handler does a binary search through the array until it finds a matching entry and loads it into the TLB. The u-boot image itself is covered by a fixed TLB entry which is never replaced. This makes the 'saveenv' command work again on ATNGW100 and other boards using the CFI driver, hopefully without breaking any rules. Signed-off-by: Haavard Skinnemoen

avr32: Use uncached() macro to get an address for SDRAM init

2010-09-03T13:12:52Z

The paging system which is required to set up caching properties has not yet been initialized when the SDRAM is initialized. So when the map_physmem() function is converted to return the physical address unchanged, the SDRAM initialization will break on some boards. The avr32-specific uncached() macro will return an address which will always cause uncached accessed to be made. Since this happens in the board code, using avr32-specific features should be ok, and will allow the SDRAM initialization to keep working. Signed-off-by: Haavard Skinnemoen

MIMC200: reduce LCD pixclock

2009-08-11T11:58:26Z

The initial pixclock for the MIMC200 board is wrong (and causes screen corruption due to DMA underruns). This patch simply reduces the pixel clock to fix the problem. Signed-off-by: Mark Jackson

Fix all linker script to handle all rodata sections

2009-03-20T21:39:12Z

A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho

Setup extra MIMC200 chip selects

2009-02-23T10:16:14Z

Added code to setup the extra Flash and FRAM chip selects as used on the MIMC200 board. V2 moves the init code from the common "cpu.c" file into the board specific setup file. Signed-off-by: Mark Jackson Signed-off-by: Haavard Skinnemoen

MIMC200: tidy GCLK init code

2009-02-23T10:13:55Z

Change the MIMC200 startup code to use the built-in (rather than hard-coded) funtions for setting up gclk outputs. We'll also move the code to the new, more-appropriate board_postclk_init() routine. Signed-off-by: Mark Jackson Signed-off-by: Haavard Skinnemoen
