(beginner) Kernel fail during local_irq_enable()

I work on a custom board based on MPC8xx. The bootloader on it is a ppcboot 1.1.5. I'm a beginner with Linux port and ppc. I'm trying to pass the board working with a 2.4.4 kernel to a 2.6.19 kernel from denx. The kernel hang when trying to enable interrupt in local_irq_enable() in

Re: SDRAM failures on MPC5200B

A follow-up: The first version of our termination network was based on the Lite5200 reference design, but was confirmed by Freescale to be inadequate. We revised the hardware per their errata, terminating both ends of the data bus. This fixed the problem. Thanks for the helpful feedback.

[PATCH v2] [POWERPC] Optimize counting distinct entries in the relocation sections

When a module has relocation sections with tens of thousands worth of entries, counting the distinct/unique entries only (i.e. no duplicates) at load time can take tens of seconds and up to minutes. The sore point is the count_relocs() function which is called as part of the architecture specific

Hi Thank you for your response. Are you *sure* it's mapped at physical address 0xe000? (ie. have you verified that you can access the device registers via u-boot or a debugger?) Yes, We have accessed the Micrel chip via U-boot setting (Micrel Chips Base addres) 0xE000 to the CS1 Start

[PATCH] powerpc: Fix fs_enet module build

If fs_enet is build as module, on PPC_CPM_NEW_BINDING platforms mii-fec/mii-bitbang should be build as module, as well. On other platforms, mii-fec/mii-bitbang must be included into the main module. Otherwise some symbols remain undefined. Additionally, fs_enet uses libphy, so add a select PHYLIB.
