x86: Move turbo_state to global_data

2017-02-07T05:07:26Z

To avoid using BSS in SPL before SDRAM is set up, move this field to global_data. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Support global_data on x86_64

2017-02-06T03:38:46Z

At present this is just an ordinary variable. We may consider making it a fixed register in the future. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Prepare configuration tables in dedicated high memory region

2016-05-23T07:18:00Z

Currently when CONFIG_SEABIOS is on, U-Boot allocates configuration tables via normal malloc(). To simplify, use a dedicated memory region which is reserved on the stack before relocation for this purpose. Add functions for reserve and malloc. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: broadwell: Add support for SDRAM setup

2016-03-17T02:27:26Z

Broadwell uses a binary blob called the memory reference code (MRC) to start up its SDRAM. This is similar to ivybridge so we can mostly use common code for running this blob. Signed-off-by: Simon Glass Acked-by: Bin Meng

x86: tsc: Remove legacy timer codes

2015-12-01T13:26:35Z

Now that we have converted all x86 boards to use driver model timer, remove these legacy timer codes in the tsc driver. Note this also removes the TSC_CALIBRATION_BYPASS Kconfig option, as it is not needed with driver model. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Remove MIN_PORT80_KCLOCKS_DELAY

2015-12-01T13:23:51Z

This is not referenced anywhere. Remove it, as well as tsc_base_kclocks and tsc_prev in the global data. Signed-off-by: Bin Meng Acked-by: Simon Glass Fix 'Reomve' typo: Signed-off-by: Simon Glass

x86: Move the GDT into global_data

2015-08-14T15:50:10Z

Rather than keeping track of the Global Descriptor Table in its own memory we may as well put it in global_data with everything else. As a first step, stop using the separately allocated GDT. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add support for passing tables into U-Boot

2015-08-05T14:44:07Z

The EFI stub provides information to U-Boot in a table. This includes the memory map which is needed to decide where to relocate U-Boot. Collect this information in the early init code and store it in global_data. Fix up the BIST code at the same time since we don't have it when booting from EFI and can assume it is 0.

x86: Allow use of global_data with EFI

2015-08-05T14:42:41Z

On x86 the global_data pointer is provided through a somewhat-bizarre and x86-specific mechanism: the F segment register is set to a pointer to the start of global_data, so that accesses can use this build-in register. When running as an EFI application we don't want to mess with the Global Descriptor Table (GDT) and there is little advantage (in terms of code size) to doing so. Allow global_data to be a simple variable in this case. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
