rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

at91rm9200ek: add configure target for RAM boot

2010-12-07T21:08:06Z

This patch also removes now unnecessary config.mk in board directory and make usage of new features in boards.cfg. Signed-off-by: Andreas Bießmann

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

at91rm9200ek: convert to at91

2010-10-19T13:11:46Z

This patch removes some functionality from at91rm9200ek board but the remaining functionality does now work with newer at91 code and arm-relocation. Currently missing features are: - dataflash booting (due to missing HW for testing) - MMC/SD-Card - first stage bootloader support is completely removed (not needed for NOR) Cause this board was (some days ago) reference for all at91rm9200 based boards this should be a good starting point to convert all remaining at91rm9200 borads to at91 code. Aside from that this is a good base to get some drivers between at91sam/at91rm/avr32 merged. Signed-off-by: Andreas Bießmann Signed-off-by: Reinhard Meyer

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

2010-10-18T20:07:10Z

The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

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

Write MAC address automatically on MACB-based boards

USB OHCI support for at91sam9g45 SoC

2010-06-30T19:37:36Z

Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards. Note that according to errata from Atmel, OHCI is not operational on the first revision of at91sam9g45 chip. So this patch enables OHCI support for later revisions. Signed-off-by: Sergey Matyukevich

avr32: fix linking of atstk100x and favr32 boards

2010-06-29T20:37:11Z

When building some avr32 boards out of tree (e.g. O=..) the linker script could not be found. This patch references the linker script in source tree. Signed-off-by: Andreas Bie�mann
