PPC: remove dead boards (AMX860, c2mon, ETX094, IAD210, LANTEC, SCM)

2012-10-28T19:17:25+00:00

These boards have long reached EOL, and there has been no indication
of any active users of such hardware for years.  Get rid of the dead
weight.

post: use ARRAY_SIZE

We've got a handy dandy macro already for calculating the number of
elements in an array, so use it.

ppc4xx/POST: Change ethernet test loop count to a default of 10

2010-12-17T08:44:32+00:00

This patch changes the PPC4xx ethernet POST loop test count from
currently 192 (256 - 64) to a default of 10. While doing this the max
frame size is increased. Each loop run uses a different frame size,
starting with a max of 1514 bytes, down to 64. The default loop
count of 10 can be overriden using CONFIG_SYS_POST_ETH_LOOPS in the
board config header.

The TEST_NUM loop has been removed as it was never used.

The main reason for this change is to reduce the boot time on boards
using this POST test, like the lwmon5 board. This change reduces the
boot time by about 600ms on the lwmon5 board.

ppc4xx/POST: Handle cached SDRAM correctly in Denali (440EPx) ECC POST

2010-11-28T10:06:47+00:00

This patch fixes a problem in the Denali (440EPx) SDRAM ECC POST test.
When cache is enabled in the SDRAM area, the values written to SDRAM
need to be flushed from cache to SDRAM using the dcfb instruction.

Without this patch the POST ECC test failed. Now its working again on
platforms with cache enabled in SDRAM.

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.

ppc4xx: Use common ns16550 functions in 4xx UART POST driver

2010-10-04T09:20:02+00:00

This patch changes the PPC4xx POST UART driver to use the common
NS16550 functions for receiving and sending. Additionally the
local function for SoC divisor setup are removed. Instead the
functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This
removes code duplication.

Also the common CONFIG_SYS_NS16550_COMx defines are now used
to describe the POST UART's.

And a compile breakage is fixed, introduced by a git merge of
the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to
"asm/ppc4xx.h". Fixed as well with this patch.

ppc4xx: Move ppc4xx headers to powerpc include directory

2010-09-23T07:02:05+00:00

This patch moves some ppc4xx related headers from the common include
directory (include/) to the powerpc specific one
(arch/powerpc/include/asm/). This way to common include directory is not
so cluttered with files.

ppc4xx: POST UART: Use in/out_8() io-accessor functions

2010-09-23T06:43:56+00:00

This patch fixes a problem in the PPC4xx POST UART driver. This driver
incorrectly used the in/out8() io-accessor functions. This could lead to
problems since these functions don't guarantee execution ordering. This
patch now replaces these functions with the correct ones.

Additionally the driver is converted to using the NS16550 struct instead
of macros for the register offsets.

And some common code is factored out for better maintainability.
