The PXA25x and PXA27x USB device controller register definitions are different. Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.

Related to d3930614. RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs. Therefore, we should not be unconditionally writing to RCSR from generic code. Since we now clear the RCSR status from the SoC specific PXA PM code and before reset in the arch_reset() function, the duplication in the corgi, poodle, spitz and tosa code can be removed.

Reasons: 1. straight forward: the name "LCD_COLOR_DSTN_16BPP" is much better than "LCCR0_Pas | LCCR0_Color | LCCR0_Dual" 2. by defining LCD connection types as constants, it allows only valid possibilities 3. by removing the dependency of register bits definitions, those can be later moved into the body of pxafb.c, instead of having a regs-lcd.h around Currently, only lubbock, mainstone, zylonite and littleton have been modified to support these types (see coming patches after this). Other platforms are encouraged to change their way describing the LCD controller connections. Signed-off-by: Neric miao <eric.miao@marvell.com> Cc: "Antonino A.

This is part of the effort moving peripheral registers outside of pxa-regs.h, and using ioremap() make it possible the same IP can be re-used on different processors with different registers space As a result, the fixed mapping in pxa_map_io() is removed. The regs-lcd.h can actually moved to where closer to pxafb.c but some of its bit definitions are directly used by various platform code, though this is not a good style.

s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory model (which is more dynamic than most). Instead, they had proposed to implement it with an additional path through vm_normal_page(), using a bit in the pte to determine whether or not the page should be refcounted: vm_normal_page() { ... if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) { if (vma->vm_flags & VM_MIXEDMAP) { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; #else if (!pfn_valid(pfn)) return NULL; #endif goto out; } ... } This is fine, however if we are allowed to use a bit in the pte to determine refcountedness, we can use that to _completely_ replace all the vma based schemes. So instead of adding more cases to the already complex vma-based scheme, we can have a clearly seperate and simple pte-based scheme (and get slightly better code generation in the process): vm_normal_page() { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; return pte_page(pte); #else ... #endif } And finally, we may rather make this concept usable by any architecture rather than making it s390 only, so implement a new type of pte state for this. Unfortunately the old vma based code must stay, because some architectures may not be able to spare pte bits. This makes vm_normal_page a little bit more ugly than we would like, but the 2 cases are clearly seperate. So introduce a pte_special pte state, and use it in mm/memory.c. It is currently a noop for all architectures, so this doesn't actually result in any compiled code changes to mm/memory.o. BTW: I haven't put vm_normal_page() into arch code as-per an earlier suggestion. The reason is that, regardless of where vm_normal_page is actually implemented, the *abstraction* is still exactly the same. Also, while it depends on whether the architecture has pte_special or not, that is the only two possible cases, and it really isn't an arch specific function -- the role of the arch code should be to provide primitive functions and accessors with which to build the core code; pte_special does that. We do not want architectures to know or care about vm_normal_page itself, and we definitely don't want them being able to invent something new there out of sight of mm/ code. If we made vm_normal_page an arch function, then we have to make vm_insert_mixed (next patch) an arch function too. So I don't think moving it to arch code fundamentally improves any abstractions, while it does practically make the code more difficult to follow, for both mm and arch developers, and easier to misuse.

This is preliminary since: 1. It supports only _one_ chip select at the moment. As there is no existing platforms available using two chip selects of the NAND controller, it shall really not include code for supporting the 2nd chip select for now, as such code cannot be verified. 2. It resorts to the default and simpliest memory based badblock table 3. Only limited types of nand flash are currently supported. Most PXA3xx processors come with on-chip NAND flash dies, so there isn't much flexibility for other types of NAND. 4. The NAND controller should be configured to detect the device's ID, thus making it difficult to use nand_scan_ident() to assist the detection process (though it's not impossible) TODO: fix all the above limitations of cuz :-) Signed-off-by: Neric miao <eric.miao@marvell.com> Cc: Sergey Podstavin <spodstavin@ru.mvista.com> Signed-off-by: NDavid Woodhouse <dwmw2@infradead.org>
