sh_mobile_meram: Add direct MERAM allocation API

2012-07-19T00:05:22+00:00

The API can be used to allocate and free MERAM blocks directly, without
going through ICBs.

sh_mobile_meram: Use direct function calls for the public API

2012-07-19T00:05:21+00:00

There's no reason to use abstract operation pointers to implement the
MERAM API. Replace them by direct function calls.

sh_mobile_meram: Rename operations to cache_[alloc|free|update]

2012-07-19T00:05:21+00:00

The MERAM operations meram_register, meram_unregister and meram_update
handle LCDC cache. In preparation for "raw" MERAM allocation, rename
them to more appropriate names.

fbdev: sh_mobile_meram: Remove unneeded sanity checks

2012-03-12T21:41:14+00:00

The meram_register(), meram_unregister() and meram_update() operations
check that the pointers they get from the caller are not NULL. Those
checks can be remove, as the caller already ensures that the pointers
are valid.

The platform sanity checks can also be removed, as the operations can't
be accessed without valid platform data anyway.

fbdev: sh_mobile_meram: Don't perform update in register operation

2012-03-12T21:41:13+00:00

Remove the RGB or Y/C base address update from the meram_register()
operation, as this belongs to the meram_update() operation.

fbdev: sh_mobile_meram: Remove unused sh_mobile_meram_icb_cfg fields

2012-03-12T21:41:12+00:00

The marker_icb and cache_icb fields are not used anymore, remove them.

fbdev: sh_mobile_meram: Allocate ICBs automatically

2012-03-12T21:41:11+00:00

Instead of manually specifying the ICBs to use in platform data,
allocate them automatically at runtime. The range of reserved ICBs (for
instance to be used through UIO), if any, is passed in the platform data
reserved_icbs field as a bitmask.

The MERAM registration function now returns a pointer to an opaque MERAM
object, which is passed to the update and unregistration functions.

fbdev: sh_mobile_meram: Use genalloc to manage MERAM allocation

2012-03-12T21:41:10+00:00

Instead of requiring the users to hardcode MERAM allocation in platform
data, allocate blocks at runtime using genalloc.

fbdev: sh_mobile_meram: Add struct sh_mobile_meram_icb

2012-03-12T21:41:09+00:00

The new structure stores ICB parameters for ICBs.

Instead of modifying the struct sh_mobile_meram_cfg instances passed by
callers, store the ICB parameters internally and make the public API
take const pointers to sh_mobile_meram_cfg.

fbdev: sh_mobile_meram: Make variables unsigned where applicable

2012-03-12T21:41:08+00:00

Many variables, such as loop counters, sizes and offsets, should be
unsigned integers. Make them so.
