x86: Rationalise kernel booting logic and bootstage

2013-05-13T20:33:20Z

The 'Starting linux' message appears twice in the code, but both call through the same place. Unify these and add calls to bootstage to mark the occasion. Signed-off-by: Simon Glass Reviewed-by: Michael Spang Acked-by: Graeme Russ

x86: Add basic cache operations

2013-03-04T23:57:34Z

At present most x86 cache operations are undefined. Add a basic implementation for these. Signed-off-by: Simon Glass

x86: Move gd_addr into arch_global_data

2013-02-01T20:39:42Z

Move this field into arch_global_data and tidy up. Signed-off-by: Simon Glass [trini: Add arch/x86/cpu/cpu.c changes after Graeme's comments] Signed-off-by: Tom Rini

x86: Set up the global data pointer in C instead of asm

2013-02-01T20:36:53Z

We currently assume that the global data pointer is at the start of struct global_data. We want to remove this restriction, and it is easiest to do this in C. Remove the asm code and add equivalent code in C. This idea was proposed by Graeme Russ here: http://patchwork.ozlabs.org/patch/199741/ Signed-off-by: Simon Glass [trini: Apply Graeme Russ' comments http://patchwork.ozlabs.org/patch/206305/ here, re-order] Signed-off-by: Tom Rini

x86: Add basic cache operations

2012-12-06T22:30:39Z

Add functions to enable/disable the data cache. Signed-off-by: Stefan Reinauer Signed-off-by: Simon Glass

x86: Add a default implementation for cleanup_before_linux()

2012-11-30T21:44:04Z

This function provides an opportunity for some last minute cleanup and reconfiguration before control is handed over to Linux. It's possible this may need to do something in the future, but for now it's left empty. It's set up as a weak symbol so it can be overridden if necessary on a case by case basis.

x86: Put global data on the stack

2012-11-28T19:40:03Z

Putting global data on the stack simplifies the init process (and makes it slightly quicker). During the 'flash' stage of the init sequence, global data is in the CAR stack. After SDRAM is initialised, global data is copied from CAR to the SDRAM stack Signed-off-by: Graeme Russ Signed-off-by: Simon Glass

x86: Forward declare gd_t

2012-11-28T19:40:03Z

So it can be used as a type in struct global_data and remove an ugly typecast Signed-off-by: Graeme Russ Signed-off-by: Simon Glass Acked-by: Marek Vasut
