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: 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: Big cleanup of PPC4xx defines

2009-09-11T08:35:58+00:00

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

ppc4xx: Change 4xx POST ethernet test to handle cached memory too

2007-10-31T20:21:47+00:00

This patch enables the 4xx EMAC POST driver to work too, when dcache is
enabled.

ppc4xx: Fix POST ethernet test for Haleakala

2007-10-31T20:20:51+00:00

The POST ethernet test needed to be changed to dynamically determine
the count of ethernet devices. This code is cloned from the 4xx
ethernet driver.

POST: Add option for external ethernet loopback test

2007-08-14T12:41:55+00:00

When CFG_POST_ETHER_EXT_LOOPBACK is defined, the ethernet POST
is not done using an internal loopback connection, but by assuming
that an external loopback connector is plugged into the board.
