[U-Boot-Users] [PATCH v2] PPC4xx: Correct SDRAM_MCSTAT for PPC405EX(r)
by Grant Erickson 11 Jul '08

11 Jul '08

While the PowerPC 405EX(r) shares in common the AMCC/IBM DDR2 SDRAM controller core also used in the 440SP, 440SPe, 460EX, and 460GT, in the 405EX(r), SDRAM_MCSTAT has a different DCR value. Its present value on the 405EX(r) causes a read back of 0xFFFFFFFF which causes SDRAM initialization to periodically fail since it can prematurely indicate SDRAM ready status.

[U-Boot-Users] [PATCH] PPC4xx: Add MII mode support to the EMAC RGMII Bridge

This patch adds support for placing the RGMII bridge on the PPC405EX(r) into MII/GMII mode and allows a board-specific configuration to specify the bridge mode at compile-time.

[U-Boot-Users] [PATCH] ppc4xx: Fix include sequence in 4xx_pcie.c
by Stefan Roese 11 Jul '08

11 Jul '08

This patch now moves common.h to the top of the inlcude list. This is needed for boards with CONFIG_PHYS_64BIT set (e.g. katmai), so that the phys_size_t/phys_addr_t are defined to the correct size in this driver.

[U-Boot-Users] PATCH: mpc85xx set lcb clock (CONFIG_CCB_CLCKDIV)
by John Ogness 11 Jul '08

11 Jul '08

Hi, Here is a patch to add support for manually setting the system (CCB) clock divider for MPC85xx boards. This patch introduces a new macro CONFIG_CCB_CLCKDIV, whose value should be set to the desired clock divider. If the macro is not defined, this patch has no effect. As an example, the new option can be used in the board config file like this: #define CONFIG_CCB_CLCKDIV 4 The patch is against git commit: a524e112b424c6843800ea2f19d3a8cf01d0aa94 John Ogness Signed-off-by: John Ogness <john.ogness(a)linutronix.de>
