AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed. The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board. It is essentially the same, with a few minor differences.

2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
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 <xyzzy@speakeasy.org>

2008-11-21AT91: Enable PLLB for USBStelian Pop
At least some (old ?) versions of the AT91Bootstrap do not set up the PLLB correctly to 48 MHz in order to make USB host function correctly. This patch sets up the PLLB to the same values Linux uses, and makes USB work ok on the following CPUs: - AT91CAP9 - AT91SAM9260 - AT91SAM9263 This patch also defines CONFIG_USB_STORAGE and CONFIG_CMD_FAT for all the relevant AT91CAP9/AT91SAM9 atmel boards.

2008-09-10ARM DaVinci: Fix broken HW ECC for large page NAND.Hugo Villeneuve
Based on original patch by Bernard Blackham <bernard@largestprime.net> U-boot's HW ECC support for large page NAND on Davinci is completely broken. Some kernels, such as the 2.6.10 one supported by MontaVista for DaVinci, rely upon this broken behaviour as they share the same code for ECCs. In the existing scheme, error detection *might* work on large page, but error correction definitely does not. Small page ECC correction works, but the format is not compatible with the mainline git kernel. This patch adds ECC code that matches what is currently in the Davinci git repository (since NAND support was added in 2.6.24). This makes the ECC and OOB layout written by u-boot compatible with Linux for both small page and large page devices and fixes ECC correction for large page devices. The old behaviour can be restored by defining the macro CFG_DAVINCI_BROKEN_ECC, which is undefined by default.

2008-08-31ARM DaVinci: Changing function names for EMAC driverSandeep Paulraj
DM644x is just one of a series of DaVinci chips that use the EMAC driver. By replacing all the function names that start with dm644x_* to davinci_* we make these function more portable. I have tested this change on my EVM. DM6467 is another DaVinci SOC which uses the EMAC driver and i will be sending patches that add DaVinci DM6467 support to the list soon.

2008-08-12Update MTD to that of Linux 2.6.22.1William Juul
A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.
