We should really look at making this common, either move to plat-s5p
or even into plat-samsung.

There's no real point in creaitng S5P_PA_UART, S5P_UART_OFFSET, S5P_PA_TIMER
or S5P_PA_IIC0 if all we're going to do with them is then define S3C_PA,
let's just define the S3C_PA variants directly.
As for the S5P_VA, we should create a common map-s5p.h file in plat-s5p
and use that to deifne where we put these common mappings.

This looks like a number of current UART setups, should look at
making it common too.

If we're only just mapping the block here, how have we had working code
for the s5p6440?

Why not call these init.o and clock.o? no need to have s5p6442 infront.
Plus s5p6442-clock.c isn't even in this patch, so s5p6442-clock.o shouldn't
be added here.

Same for this, mach-smdk6442.c isn't in this patch so this line shouldn't
be here.

We acutally have a code problem here, since we're relying on the
default FIFO settings and the S5P6442/S5PV210 UARTs do not use the
same UFSTAT register layout as the previous SoCs do.
arch/arm/plat-s3c/include/plat/debug-macro.S:
17 .macro fifo_level_s3c2440 rd, rx
18 ldr \rd, [ \rx, # S3C2410_UFSTAT ]
19 and \rd, \rd, #S3C2440_UFSTAT_TXMASK
20 .endm
21
22 #ifndef fifo_level
23 #define fifo_level fifo_level_s3c2440
24 #endif
25
26 .macro fifo_full_s3c2440 rd, rx
27 ldr \rd, [ \rx, # S3C2410_UFSTAT ]
28 tst \rd, #S3C2440_UFSTAT_TXFULL
29 .endm
30
31 #ifndef fifo_full
32 #define fifo_full fifo_full_s3c2440
33 #endif
Show we use the s3c2440 versions for fifo_level and fifo_full if they
have not been defined before including this file.
from arch/arm/plat-s3c/include/plat/regs-serial.h:
167 #define S3C2440_UFSTAT_TXFULL (1<<14)
171 #define S3C2440_UFSTAT_TXMASK (63<<8)
220 #define S5PV210_UFSTAT_TXFULL (1<<24)
222 #define S5PV210_UFSTAT_TXMASK (255<<16)
Note the different positions of the TXUFLL and TXMASK bits.
This means you'll ave to define your own fifo_full and fifo_level
settings and the relevant macros for them.
Further patches snipped.

This is a clarifction / extra comment on my previous review as
requested in private. Posted here as it is useful to everyone involved.

If someone had read the above comment before copying this file, they
would have realised it is un-necessary for the current support as the
UART blocks in all the s5p6440, s5p6442 and the v210 are aligned on
one-megabyte boundaries and as such are suitable for mapping on 1MiB
L1 section boundaries.
This should removed from both the 6442 and s5pv210 before submission.

again, since we're one a 1MiB boundary we can lose the + S5P_PA_UART & 0xfffff
from this.

As for the debug-macro.S core in arch/arm/plat-s3c/include/plat/debug-macro.S
you can (and it would be advisable) to add the relevant v210 macros so
that both the v210 and the 6442 can use them in their local files...
so possibly:
.macro fifo_full_v210 rd, rx
....
.endm
.macro fifo_level_v210 rd, rx
....
.endm
PS, you will want to edit the v210 code to fix this too.

You've included support for the SMDK6442 here when mach-smdk6442.c isn't
being added in this patch.
