drm/ast: Call open_key before enable_mmio in POST code

2017-02-28T03:25:32+00:00

open_key enables access the registers used by enable_mmio Signed-off-by: Y.C. Chen Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Tested-by: Y.C. Chen Cc: Signed-off-by: Dave Airlie

drm/ast: Fix test for VGA enabled

2017-02-28T03:24:53+00:00

The test to see if VGA was already enabled is doing an unnecessary second test from a register that may or may not have been initialized to a valid value. Remove it. Signed-off-by: Y.C.

drm/ast: POST code for the new AST2500

2017-02-28T03:19:01+00:00

This is used when the BMC isn't running any code and thus has to be initialized by the host. The code originates from Aspeed (Y.C. Chen) and has been cleaned up for coding style purposes by BenH.

drm/ast: Rename ast_init_dram_2300 to ast_post_chip_2300

2017-02-28T03:18:06+00:00

The function does more than initializing the DRAM and in turns calls other functions to do the actual init. This will keeping things more consistent with the upcoming AST2500 POST code. Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Tested-by: Y.C. Chen Signed-off-by: Dave Airlie

drm/ast: Factor mmc_test code in POST code

2017-02-28T03:17:30+00:00

There's a some duplication for what's essentially copies of two loops, so factor it. The upcoming AST2500 POST code adds more of them. Also cleanup return types for the test functions, most of them return a boolean, some return a u32. Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Tested-by: Y.C.

drm/ast: Fixed vram size incorrect issue on POWER

2017-02-28T03:16:14+00:00

The default value of VGA scratch may incorrect. Should initial h/w before get vram info. Acked-by: Joel Stanley Tested-by: Y.C. Chen Signed-off-by: Y.C. Chen Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Dave Airlie

drm/ast: Base support for AST2500

2017-02-28T03:15:14+00:00

Add detection and mode setting updates for AST2500 generation chip, code originally from Aspeed and slightly reworked for coding style mostly by Ben. This doesn't contain the BMC DRAM POST code which is in a separate patch. Signed-off-by: Y.C. Chen Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Signed-off-by: Dave Airlie

drm/ast: Fix calculation of MCLK

2017-02-28T03:14:22+00:00

Some braces were missing causing an incorrect calculation. Y.C. Chen from Aspeed provided me with the right formula which I tested on AST2400 and 2500. The MCLK isn't currently used by the driver (it will eventually to filter modes) so the issue isn't catastrophic. Also make the printed value a bit more meaningful Signed-off-by: Benjamin Herrenschmidt Acked-by: Joel Stanley Tested-by: Y.C. Chen Signed-off-by: Dave Airlie

drm/ast: const'ify mode setting tables
