[U-Boot] [PATCH v3 0/7] tegra: Add NAND flash support
by Simon Glass 28 Apr '12

28 Apr '12

This series adds NAND flash support to Tegra and enables it on Seaboard. Included here is a proposed device tree binding with most of the properties private to "nvidia,". The binding includes information about the NAND controller as well as the connected NAND device. The Seaboard has a Hynix HY27UF4G2B. The driver supports ECC-based access and uses DMA and NAND acceleration features of the Tegra SOC to provide access at reasonable speed. Changes in v2: - Add new patch to align default buffers in nand_base - Added comment about the behaviour of the 'resp' register - Call set_bus_width_page_size() at init to report errors earlier - Change set_bus_width_page_size() to return an error when needed - Change timing structure member to u32 to match device tree - Check for supported bus width in board_nand_init() - Fix tegra nand header file to remove BIT defines - Implement a dummy nand_select_chip() instead of nand_hwcontro() - Make nand_command() display an error on an unknown command - Minor code tidy-ups in driver for style - Move cache logic into a separate dma_prepare() function - Remove CMD_TRANS_SIZE_BYTESx enum - Remove space after casts - Remove use of 'register' variables - Rename struct nand_info to struct nand_drv to avoid nand_info_t confusion - Support 4096 byte page devices, drop 1024 and 2048 - Tidy up nand_waitfor_cmd_completion() logic - Update NAND binding to add "nvidia," prefix - Use s32 for device tree integer values Changes in v3: - Add reg property for unit address (should be used for chip select) - Change note in fdt binding about the need for a hardware-specific binding - Fix up typos in fdt binding, and rename the file - Update fdt binding to make everything Nvidia-specific Jim Lin (1): tegra: nand: Add Tegra NAND driver Simon Glass (6): nand: Try to align the default buffers fdt: Add debugging to fdtdec_get_int/addr() tegra: Add NAND support to funcmux tegra: fdt: Add NAND controller binding and definitions tegra: fdt: Add NAND definitions to fdt tegra: Enable NAND on Seaboard arch/arm/cpu/armv7/tegra2/funcmux.c | 7 + arch/arm/dts/tegra20.dtsi | 6 + arch/arm/include/asm/arch-tegra2/funcmux.h | 3 + arch/arm/include/asm/arch-tegra2/tegra2.h | 1 + board/nvidia/dts/tegra2-seaboard.dts | 16 + .../nand/nvidia,tegra20-nand.txt | 68 ++ drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/nand_base.c | 3 +- drivers/mtd/nand/tegra2_nand.c | 1095 ++++++++++++++++++++ drivers/mtd/nand/tegra2_nand.h | 257 +++++ include/configs/seaboard.h | 9 + include/fdtdec.h | 1 + include/linux/mtd/nand.h | 7 +- lib/fdtdec.c | 23 +- 14 files changed, 1487 insertions(+), 10 deletions(-) create mode 100644 doc/device-tree-bindings/nand/nvidia,tegra20-nand.txt create mode 100644 drivers/mtd/nand/tegra2_nand.c create mode 100644 drivers/mtd/nand/tegra2_nand.h -- 1.7.7.3

[U-Boot] [PATCH] PowerPC: Change -fpic flag to -fPIC flag in the config.mk
by Chunhe Lan 27 Apr '12

27 Apr '12

The -fPIC/-fpic flag belongs with -mrelocatable. The -fpic flag can limit the size of the GOT and produce smaller binaries, so it causes some GOT entries to be lost in the gcc 4.6 version. But -fPIC flag allows the maximum possible size of the GOT entries. However, currently -mrelocatable promotes -fpic flag to -fPIC flag. This reverts that portion of the commit 33ee4c92339ee386662c0ee2d221098c5cc8b07e.

[U-Boot] [SOT] linker scripts
by Jason 27 Apr '12

27 Apr '12

All, I know this is a little off topic, but u-boot is the only project I've found implementing a feature I'd like to add to a project. Specifically, the macro U_BOOT_CMD() and it's use of section(".u_boot_cmd"). I'd like to implement something similar in a userspace C program, but I can't get it to work. A lot of my searches on the net for my various errors leads me to believe I should let gcc do the linking and not mess with ld. I've gotten to the point where it compiles cleanly, but then I get 'No such file or directory" from bash when trying to run the resulting executable. (Using ld) Is there a succinct way to use the modified output of 'ld -v' from gcc so that I can place the array of structs between _blah_start and _blah_end? I've tried 'gcc -Wl,-T,mylink.lds -Wl,-u_blah_thisone ...' and that compiles fine, and runs, but there is no struct found when I iterate from _blah_start to _blah_end. The output of 'strings a.out | grep _blah' gives only _blah_end. I'm a bit out of my depth here. Any help appreciated. thx, Jason.

It's a feature of the core. Change your code to enable it for e500 and e500v2, and then test it on a few systems to make sure it works. We don't want to have to enable it for each SoC, one by one.
