ppc4xx: Fix 460EX errata with CPU lockup upon high AHB traffic

2008-06-30T13:20:41+00:00

This patch implements a fix provided by AMCC so that the lockup upon
simultanious traffic on AHB USB OTG, USB 2.0 and SATA doesn't occur
anymore:

Set SDR0_AHB_CFG[A2P_INCR4] (bit 24) and clear SDR0_AHB_CFG[A2P_PROT2]
(bit 25) for a new 460EX errata regarding concurrent use of AHB USB OTG,
USB 2.0 host and SATA.

This errata is not officially available yet. I'll update the comment
to add the errata number later.

ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1

2008-06-03T18:21:53+00:00

This patch removes all SDRAM related defines from the PPC4xx headers
ppc405.h and ppc440.h. This is needed since now some 405 PPC's use
the same SDRAM controller as 440 systems do (like 405EX and 440SP).

It also introduces new defines for the equipped SDRAM controller based on
which PPC variant is used. There new defines are:

used on 405GR/CR/EP and some Xilinx Virtex boards.

used on 440GP/GX/EP/GR.

used on 440EPx/GRx.

used on 405EX/r/440SP/SPe/460EX/GT.

Big white-space cleanup.

2008-05-20T22:14:08+00:00

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

lwmon5: watchdog POST fix

2008-04-25T09:35:32+00:00

Use the GPT0_MASKx registers as the temporary storage for watch-dog
timer POST test instead of GPT0_COMPx. The latter
(GPT0_COMP1..GPT0_COMP5) are used for the log-buffer header.

ppc4xx: Add AMCC Glacier 406GT eval board support

2008-03-27T08:54:41+00:00

This patch adds support for the AMCC Glacier 460GT eval board.
The main difference to the Canyonlands board are listed here:

- 4 ethernet ports instead of 2
- no SATA port
- no USB port

Currently EMAC2+3 are not working. This will be fixed in a later
release.

The patch introduces the alternative configuration of the log buffer for the lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5).

2008-03-18T21:24:48+00:00

 To enable this, alternative, configuration the U-Boot board configuration
file for lwmon5 includes the definitions of alternative addresses for header
(CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR).

 The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set,
and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the
lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).

* External Watchdog test;
* dsPIC tests;
* FPGA test;
* GDC test;
* Sysmon tests.
