espi enable/disable issue

2011-09-16 Thread Michele Jr De Candia
Hi all, we're using your driver for espi controller on P1015 freescale micro. We're testing an issue trying to do multiple operation into a single chip select window. We've noted that the driver disables and enables the ESPI_SPMODE[EN] bit in order to change the ESPI_SPMODE x register; probably

Timer interrupt on Linux 3.0.3

2011-09-16 Thread Vineeth
Hi, We are porting Linux on MPC7410 based board. As there was some issue with the processor DECrementer and timebase registers, we were using an external count down timer as our DECementer. We used timer_interrupt() function in arch/powerpc/kernel/time.c as our interrupt handler. Things were

[PATCH] powerpc/e5500: Set r5 to point to cpu spec in setup_cpu_e5500()

From: Laurentiu Tudor laurentiu.tu...@freescale.com e500mc and e5500 share some eary setup code that need r5 to point to the cpu spec structure. setup_cpu_e500mc() sets it but setup_cpu_e5500() didn't. This caused a crash on 32 bit e5500 running under hypervisor, when __setup_e500mc_ivors()

[PATCH 1/2] powerpc: respect mem= setting for early memory limit setup

2011-09-16 Thread Kumar Gala
For those MMUs that have some form of bolt'd linear mapping (TLB) required its rare that one ever sets mem= smaller than the size of that mapping. However, on Book-E 64 parts the initial linear mapping is quite large (1G) so its quite reasonable that mem= is set smaller than that. We need to

[PATCH 2/2] powerpc/fsl-booke: Fix setup_initial_memory_limit to not blindly map

2011-09-16 Thread Kumar Gala
On FSL Book-E devices we support multiple large TLB sizes and so we can get into situations in which the initial 1G TLB size is too big and we're asked for a size that is not mappable by a single entry (like 512M). The single entry is important because when we bring up secondary cores they need
