What does the "define only one of next 3" part mean?

ah.. SMDKC100 can boot by onenand, nand and flash.
that means.. must define one of three..
anyway it will be deleted.

Adds new board SMDKC100 that uses s5pc100 SoC
Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
Signed-off-by: HeungJun, Kim <riverful.kim@samsung.com>
---
Changes since v1:
- arrange env values for more readable
- make C struct instead of base+offset
- use MACH_TYPE_SMDKC100 directly
- fix the CONFIG_SYS_HZ to 1000
- enable LOADB, LOADS, BOOTD, XIMG, FPGA
Changes since v2:
- remove <asm/sizes.h> and SZ_XX defines
- remove the define of machine type
- remove the unnecessary comment

Where is CONFIG_ONENAND_IPL defined ?
If it is not being used, the #ifndef logic should be reduced.

Hi Tom,
Others may disagree, but I'm personally opposed to creating
board/vendor-specific doc/README.<board> files in most cases. My logic
is that the people that are compiling and using U-Boot on my company's
boards will have bought the boards from us, and we should be the ones
providing them documentation. eg I would guess the vast majority of
board vendors don't say "for board information consult
doc/README.<board> in the U-Boot source code", they provide a PDF, text
document, datasheet, etc about the board and how it can be used. Thus
the doc/README.<board> doesn't really provide any useful info.
I think the doc/README.<board> files have a tendency to get out of date,
reference old commands, etc so are often not the best source of
reference anyway. eg take a look at doc/README.m5373evb. I'd argue a
lot of that info isn't necessary, and some of its duplicated in other
places.
I only care because I hate having to pick through 10 board-specific
README files every time I make a change the renames a command, adds a
new command, changes a CONFIG_XYZ name, etc:)
I think README files are good in general, but board-specific details
should be documented elsewhere such as a product manual.
Anyway, that's my $.02.
Best,
Peter

Slugfest over documentation!
I can see you point. If you have the board you likely have the user manual.
In no way do I want a user manual.
Mostly what I am looking for brief product description and a list of the
configs. Maybe some hints if the setup is tricky. README.omap3 contains
writeups on 6 boards, each get about 10 lines.
The vendor readme is also good if you want to convey board family u-boot
interfaces to other developers. See my writeup of omap gpio in omap3.

Nothing gets me more worked up than a documentation discussion:)

The README.omap3 looks decent, but even that I would personally have a
few issues with the following:
1. The list of omap3 boards is going to get out of date quickly when
people don't update README.omap3. Eg devkit8000 already isn't in the
list:)
2. I still think the details of how to configure U-Boot for a board, use
the ecc commands, and gpio interfaces would still be better placed in a
User's Manual. New users will use the User's Manual and experienced
users will know how to dig through the code - eg I'm not sure who will
reference README.omap3:). Those command names and config names will
probably change at some point in the future, and there's a decent chance
README.omap3 won't be similarly updated.

I see your point. If it were me, I'd throw that documentation in the
omap3 gpio driver itself. Its much more likely to be kept in sync when
code changes, and if someone is writing low-level U-Boot code, I'd hope
they'd be smart enough to track down the gpio driver they need to use.

OK, I missed that point. SOC documentation does seem more fitting. I
personally think low-level details shouldn't be in the SOC doc however.
For example, take a look at README.blackfin. There's nothing I could
ever change about U-Boot which would require this file to be updated,
which is perfect!

I think this is debatable. I'd guess most board maintainers don't
follow the list closely or care enough to monitor every change and
determine if they need to update their board's README file. So if the
person making a large change doesn't update relevant READMEs, no one
will. Eg, no one added devkit8000 to README.omap3.

Kyungmin Park sent the patch that is supported onenand_ipl for s5pc1xx.
but not yet applied onenand_ipl patch for s5pc1xx.
When that patch is applied, we need these logic.
If necessary, I'll delete these logic until apply the patch.

If the patch already exits, it would be better if it was in this
patchset. Can we get the onenand_ipl patch ?

please see below link
http://lists.denx.de/pipermail/u-boot/2009-August/059590.html
As you seen, that patch just prepare to add s5pc100 soc
actually we need more patches for add board files into onenand_ipl
and add #ifndef logic at arm_cortaxa8/start.S
so, I plan them to next patch
How you think?
Thanks

To support the s5pc1xx OneNAND IPL. It needs to refactor the current
OneNAND IPL.
Now I refactor the OneNAND IPL code first and then I will send a
OneNAND IPL codes for s5pc1xx.
I want to leave current patch as is. Since If we delete the OneNAND
IPL codes. No one can refer the codes. I mean OneNAND IPL parts
contains clock and memory configuration. These are helpful to someone
who use NAND or NOR.
Thank you,
Kyungmin Park

Yes. Leaving this patch as-is is Ok.
Please refactor the old patch and include it as this patch's
dependant in the next revision of s5pc1xx patch set.

Adds new board SMDKC100 that uses s5pc100 SoC
Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
Signed-off-by: HeungJun, Kim <riverful.kim@samsung.com>
---
Changes since v1:
- arrange env values for more readable
- make C struct instead of base+offset
- use MACH_TYPE_SMDKC100 directly
- fix the CONFIG_SYS_HZ to 1000
- enable LOADB, LOADS, BOOTD, XIMG, FPGA
Changes since v2:
- remove <asm/sizes.h> and SZ_XX defines
- remove the define of machine type
- remove the unnecessary comment
Changes since v3:
- add README.s5pc1xx file

+Summary
+=======
+
+This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx
+family of SoCs (S5PC100 [1] and S5PC110).
+
+Currently the following board is supported:
+
+* SMDKC100 [2]
+
+Toolchain
+=========
+
+While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
+with -march=armv5 to allow more compilers to work. For U-Boot code this has
+no performance impact.
+
+Build
+=====
+
+* SMDKC100
+
+make smdkc100_config
+make
+
+
+Interfaces
+==========
+
+cpu
+
+To check SoC:
+
+ if (cpu_is_s5pc100())
+ printf("cpu is s5pc100\n");
+
+ or
+
+ if (cpu_is_s5pc110())
+ printf("cpu is s5pc110\n");
+
+gpio
+ not supported yet.
