2013-01-30MIPS: qi_lb60: remove custom u-boot.lds scriptGabor Juhos
Remove the board specific linker script. It is not needed anymore, the unified MIPS linker script can be used instead. The qi_lb60 target produces a slightly different image after the change than before. The value of 'num_got_entries' symbol is different: @@ -49,7 +49,7 @@ 801000b4: 80122d00 lb s2,11520(zero) 801000b8: 80123500 lb s2,13568(zero) 801000bc: 80123ef8 lb s2,16120(zero) -801000c0: 00000139 0x139 +801000c0: 00000136 tne zero,zero,0x4 801000c4 <in_ram>: 801000c4: 8d0bfffc lw t3,-4(t0) This is caused by the different placement of the '__got_start' and '__got_end' symbols between the board specific scrip and the unified script. board specific script: __got_start = .; .got : { *(.got) } __got_end = .; unified script: .got : { __got_start = .; *(.got) __got_end = .; } Despite this difference, the resulting images are functionally identical.

2013-01-30MIPS: remove OUTPUT_FORMAT from linker scriptsGabor Juhos
The OUTPUT_FORMAT command in linker scripts was always misused due to some endianess and toolchain problems. Use GCC flags to ensure proper output format, and get rid of the OUTPUT_FORMAT commands in the board specific u-boot.lds files.

2012-10-22common: Discard the __u_boot_cmd sectionMarek Vasut
The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

2012-10-22common: Add .u_boot_list into all linker filesMarek Vasut
Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Joe Hershberger <joe.hershberger@gmail.com> Cc: Mike Frysinger <vapier@gentoo.org>
2011-10-12MIPS: Jz4740: Add qi_lb60 board supportXiangfu Liu
Add support for the qi_lb60 (a.k.a QI Ben NanoNote) clamshell device from Qi hardware: http://en.qi-hardware.com/wiki/Ben_NanoNote http://en.qi-hardware.com/wiki/Main_Page http://en.wikipedia.org/wiki/Qi_hardware This Jz4740-based clamshell device does not use NOR flash to boot. The initial bring-up assumes that U-Boot is directly loaded into SDRAM using USB boot tool, and starts from 0x80100000. About USB boot tool ------------------- Jz4740 is one of the XBurst processors with USB boot functionality supported. The CPU can boot from a small ROM in the LSI, initialize CPU and USB module, then wait for USB commands from the USB host. We can send 8 KB binary data to the CPU cache using USB boot tool. USB boot tool is available to the public at Ingenic website. Also there is an alternative Debian package named xburst-tools.
