rename _end to __bss_end__

2011-03-27T17:18:37+00:00

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.

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

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.

Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE

2010-10-18T20:07:10+00:00

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.

nios2: remove EP1C20, EP1S10, EP1S40 boards

2010-07-12T15:40:12+00:00

The example configuration files of nios2-generic board can generated
binary to run on the EP1C20, EP1S10, and EP1S40 boards. So the three
boards can be removed.

With nios2-generic approach, the fpga parameter header file can
be generated from hardware designs using tools. Porting u-boot for
nios2 boards is simplified. Vendors can supply their fpga parameter
file or patches to add a new nios2-generic board instance. There is
no need to include other boards support for nios2 in the u-boot
mainline.

nios2: add spi flash support to nios2-generic board

2010-07-12T15:35:30+00:00

This patch enables the altera_spi and spi_flash drivers for the
nios2-generic board. It allows access to the EPCS/SPI flash on
the Altera EP1C20 board.

nios2: add gpio support to nios2-generic board

2010-05-28T14:56:03+00:00

This patch adds gpio support of Altera PIO component to the
nios2-generic board. Though it drives only gpio_led at the
moment, it supports bidirectional port to control bit-banging
I2C, NAND flash busy status or button switches, etc.
