We update the comment in make_cs1_contiguous() to be a little bit
more clear (it's been copy/pasted from other silicons) and then
explain in dram_init() why we need to always try this.
Note that in the previous behavior we were always calling this on
boards that never had cs1 populated anyhow so making sure we do
this always is fine and will correct things like omap3evm detecting
an invalid amount of memory (384MB).

Since we go through the sequence to setup the SDRC timings more than
once, break this logic out into its own function and have that function
call mem_ok() to make sure the memory is usable.

It's possible to need to call this function on the same banks multiple
times so we want to be sure that 'pos A' is cleared out again at the
end.

This adds the optimal SDRC autorefresh control register values for
100Mhz, 133MHz, 165MHz and 200MHz clocks. We switch to using this
to provide the default 165MHz value.

You should use something like that here:
#define OMAP3_SDP_SDRC_xx_SHIFT 8
#define OMAP3_SDP_SDRC_yy (1 << 0)
#define SDP_3430_SDRC_RFR_CTRL_200MHz ((0x5e6 << OMAP3_SDP_SDRC_xx_SHIFT) |
OMAP3_SDP_SDRC_yy)
of course with the right "names" for xx and yy, I have not
the cpu doc@hand actual.

Really?
Using defines for the number of bits something gets shifted IN A DEFINE?
Doesn't that just obscure how it works?
And filling defines with shifts of ZERO bits just creates more noise.

OK, I hadn't forgotten about this, I've just been a bit busy. I broke
out the TRM, split these values out into binary and, breaking it out
into shifts won't help make it more understandable. It needs a better
comment, which I will happily do. Bits 1:0 are autofresh enable is 0x1
and 0x2/0x3 are bursts. 7:2 are reserved (as are 24:31) and 8:23 are
autorefresh counter value.

OK, what I've got now is a macro to calculate the MCFG values based on a
few inputs. What I don't think helps readability is doing:
#define V_MCFG_CASWIDTH_SHIFT 20
#define V_MCFG_CASWIDTH (0x3 << V_MCFG_CASWIDTH_SHIFT)
when
#define V_MCFG_CASWIDTH (0x3 << 20) /* 20:23 */
will do.
It can make sense in places where it's not otherwise clear why you're
doing a shift but in these cases

This changes to making the board be responsible for providing the
memory initialization timings in SPL and converts the devkit8000
to this framework. In SPL we try and initialize both CS0 and CS1.

A number of boards are populated with a PoP chip for both DDR and NAND
memory. Other boards may simply use this as an easy way to identify
board revs. So we provide a function that can be called early to reset
the NAND chip and return the result of NAND_CMD_READID. All of this
code is put into spl_id_nand.c and controlled via CONFIG_SPL_OMAP3_ID_NAND.

Please substitute this magic values through defines.

OK, I've clarified the original code and then done the same to this code.

This introduces 200MHz Micron parts timing information based on x-loader
to <asm/arch-omap3/mem.h>. The memory init logic is also based on what
x-loader does in these cases. Note that while previously u-boot would
be flashed in with SW ECC in this case it now must be flashed with HW
ECC. We also change CONFIG_SYS_TEXT_BASE to 0x80100000.

I'm not sure that buys us anything, honestly. Perhaps just a comment to
look it up in drivers/mtd/nand/nand_ids.c ?

Well, as I say in the comment, we can't, at least without a big rewrite
of <asm/arch-omap3/mem.h>. But, I'll see how bad it gets to do that I
suppose. Thanks.

Add Hynix 200MHz timing information to <asm/arch-omap3/mem.h>. We
don't calculate the MCFG value here for the Micron parts as the provided
one assumes a memory size which is incorrect. This also changes
CONFIG_SYS_TEXT_BASE to 0x80100000.
