[PATCH 1/5] ARM: OMAP2/3/4: Split OMAP2_IO_ADDRESS to L3 and L4

[PATCH 1/5] ARM: OMAP2/3/4: Split OMAP2_IO_ADDRESS to L3 and L4

[Santosh Shilimkar]

This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and
OMAP2_L4_IO_ADDRESS to reclaim more IO space.

The omap_read*() and omap_write*() functions will work only over 
L4 address space. Current omap kernel stack uses these functions 
only to access registers over L4 io address space

[PATCH 2/5] ARM: OMAP2/3/4: Remap L3, L4 to get more kernel io address space

[Santosh Shilimkar]

This patch remap L3 and L4 io space to get more kernel address space.
With this patch, 512 MB of IO space is reclaimed.
Some more combinations are possible but to make it uniform across
OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen

Once this is reviewed and tested sufficiently, a documentation entry can
be created to ease up reading and debugging.
Like "Documentation/arm/omap/io_map.txt"

That sure is a big cleanup patch and would take patience to complete!!

There is no reclaim of space with this patch. Its done with [2/5]

This patch only changes the macro definitions but the offsets are still the same as in old code.
So the description needs to be more explicit as to why you introduced L3/L4 macro split.

Another suggestion to minimize the so intrusive code change: As per the wiki approach: [1]
Lot of code will remain un-touched if you re-used the existing IO_OFFSET macro as follows --- 
---
#define L3_IO_OFFSET		0x90000000
#define __L3_IO_ADDRESS(pa)	((pa) + L3_IO_OFFSET)/* Works for L3 */
#define __OMAP2_L3_IO_ADDRESS(pa)	((pa) + L3_IO_OFFSET)/* Works for L3 */
#define l3_io_v2p(va)		((va) - L3_IO_OFFSET)/* Works for L3 */
 
#define IO_OFFSET		0xb2000000
#define __IO_ADDRESS(pa)	((pa) + IO_OFFSET)/* Works for L4  */
#define __OMAP2_IO_ADDRESS(pa)	((pa) + IO_OFFSET)/* Works for L4 */
#define io_v2p(va)		((va) - IO_OFFSET)/* Works for L4*/
---

This way you don't have to introduce new L4 macro at all => much lesser code impact.

[1] http://wiki.davincidsp.com/index.php/HOWTO_Support_512MB_SDRAM

>
>The omap_read*() and omap_write*() functions will work only over
>L4 address space. Current omap kernel stack uses these functions
>only to access registers over L4 io address space

Since the patch touches all IP blocks in OMAP, 
what if put a check in omap_read*/omap_write* if anyone passes an L3 address and return a KERN_ERR

Earlier code it was possible to pass L3 as well as L4 addresses to this function.
An Error log will surely go a long way in debug.

Yes comment is valid. I wanted to put - "This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to enable freeing up of more IO space.

Initially I thought about this but later preferred to split it. The only change what you are suggesting is instead of calling "OMAP2_L4_IO_ADDRESS", we keep that as "OMAP2_IO_ADDRESS". But the idea was to differentiate between various IO accesses because at some point of time all these has to be removed in favor of ioremap() + read*()/write*() one by one and that time this would be beneficial.

Does that mean all drivers, including the ones in other trees like camera, 
dss etc need to be modified if they are using IO_ADDRESS macros. The idea of 
having a macro as below was to reduce this impact.

#define __IO_ADDRESS(pa) ((pa) >= L3_34XX_PHYS ?   ((pa) + L3_IO_OFFSET) : 
((pa) + IO_OFFSET))

Going forward yes.  Refer the mailing thread comments from Tony/Kevin/Richard on below thread.
