2015-09-11arm: spear: Add command to switch between 1-bit HW ECC and SW BCH4Stefan Roese
This patch adds the "nandecc" command to switch between the SPEAr600 internal 1-bit HW ECC and the 4-bit SW BCH4 ECC. This can be needed to support NAND chips with a stronger ECC than 1-bit, as on the x600. And to dynamically switch between both ECC schemes for backwards compatibility.

2015-08-28arm: spear: Enable caches on SPEArStefan Roese
The designware ethernet driver supports d-cache now. So there is nothing stopping us now to enable the caches completely on SPEAr. Tested on SPEAr600 x600 board. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: Vipin Kumar <vk.vipin@gmail.com>
2015-08-28arm: spear: Move to common SPL infrastructureStefan Roese
The SPL implementation for SPEAr600 is older than the common SPL infrastructure. This patch now moves the SPEAr600 SPL over to the common SPL code. Tested on the only SPEAr board that currently uses SPL in mainline U-Boot, the x600.

2015-08-19usb: spear: Add support for both SPEAr600 EHCI controllersStefan Roese
USB EHCI on SPEAr600 has not been tested for a while. The base controller addresses are missing. This patch adds the defines to the header. And adds the missing code.

2014-10-29i2c: designware: Convert driver to multibus/multiadapter frameworkStefan Roese
In preparation for the SoCFPGA support of the designware I2C driver, convert this driver to the common CONFIG_SYS_I2C framework. This patch converts all users of this driver, this is: - ST spearxxx boards - AXS101 (ARC700 platform) I couldn't test this patch on those boards. Only compile tested for all spear boards. And tested on SoCFPGA.

2014-05-15arm: move exception handling out of start.S filesAlbert ARIBAUD
Exception handling is basically identical for all ARM targets. Factorize it out of the various start.S files and into a single vectors.S file, and adjust linker scripts accordingly. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

2013-12-07arm: keep all sections in ELF fileAlbert ARIBAUD
Current LDS files /DISCARD/ a lot of sections when linking ELF files, causing diagnostic tools such as readelf or objdump to produce partial output.

'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed.

2013-03-15Replace __bss_end__ with __bss_endSimon Glass
Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-12Remove linker lists (LGAs) from SPL linker scriptsAlbert ARIBAUD
Many SPL linker scripts needlessly include linker lists (aka LGAs). Remove them whenever possible; keep it only in the seven am335x_evm variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot), where there is actual content in output section .u_boot_list.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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 <sebastien.carlier@gmail.com>
