The 'clean' target has been removing all of spl but not u-boot itself.
For consistency and ease of testing, only remove SPL binaries / maps in
the clobber target, just like for full U-Boot

Only omap4/5 currently have a meaningful set of display text and overo
had been adding a function to display nothing. Change how this works to
be opt-in and only turned on for omap4/5 now.

This detection code doesn't (and can't) do anything currently, so
remove.

- Remove includes we don't need
- Switch some printf statements to puts
- Convert some printf statements to debug, introduce new puts statements
- In most cases saying just "No mkimage signature, assuming
u-boot.bin" or similar is sufficient. This also means the non-DEBUG
case doesn't need printf, in the core of SPL.
- The other case here is that PLAIN_VERSION provided what we wanted
already, so just use it.

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards. We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging
constant strings in objects. Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.
Signed-off-by: Tom Rini <trini@ti.com>

Changes in v2:
- Place files into common/spl (due to gcc bug #54303) and include/spl.h
- Reorder all of the patches that used to follow this to precede.

From: Tom Rini @ 2012-08-20 16:45 UTC (permalink / raw)
To: u-boot
- Convert the non-relocation part of board_init_f to spl_board_init,
turn on CONFIG_SPL_BOARD_INIT in the configs.
- Remove duplicated code.
- Add spl_boot_device() that returns the statically chosen boot device.
Signed-off-by: Tom Rini <trini@ti.com>
---
Changes in v2:
- Add CONFIG_SYS_SPL_MALLOC_START / SIZE defines from Christian Riesch
- Add arch/arm/cpu/arm926ejs/davinci/config.mk to build u-boot.ais

I tested the patchset on the LogicPD AM1808 experimenter's kit:
make da850evm
and flashing to SPI flash with
mono sfh_OMAP-L138.exe -targetType AM1808 -p /dev/ttyUSB0 -flash_noubl
u-boot.ais
The board boots up fine, but after pressing the reset button or
issuing the u-boot "reset" command, it is dead. Only power-cycling
helps. Before enabling the SPL framework in this patch reset works
fine. Any ideas?
Regards, Christian

I tried testing the same on omap-l138 (the entire patch set) for SPI
boot mode itsef, unfortunately the board doesn't even come up. Any Ideas ?

Confirmed, and I'll update the README to say that is how you can write
the u-boot.ais in recovery mode.

OK, I don't like the SPL malloc fix from before and I think it just
masked, partially, a real problem. The SPI code did not change in the
framework. And the very basic framework does not require malloc. I'm
going to poke around and see what I can see, but more eyes would be
welcome.

OK, got it, and a v3 shortly. In short, using CONFIG_SPL_BOARD_INIT as
the hook for doing our low-level init isn't completely sufficient, so
I've reworked things a little more and tossed in another hook point.
Now I'm also seeing the initial console output I had been missing.

+Summary
+=======
+The README is for the boot procedure used for the LogicPD AM1808 EVM.
+
+The board is booted in three stages. The initial bootloader which executes
+upon reset is the Rom Boot Loader(RBL) which sits in the internal ROM. The
+RBL initialises the memory and the SPI controller and reads the AIS image
+starting at block 0. This image can contain both the SPL and U-Boot
+binaries.
+
+AIS is an image format defined by TI for the images that are to be
+loaded to memory by the RBL. The image is divided into a series of
+sections and the image's entry point is specified. Each section comes
+with meta data like the target address the section is to be copied to
+and the size of the section, which is used by the RBL to load the
+image. At the end of the image the RBL jumps to the image entry
+point.
+
+The secondary stage bootloader(spl) which is loaded by the RBL then loads
+the u-boot from a predefined location in SPI to DDR and jumps to the u-boot
+entry point.
+
+
+Compilation
+===========
+To build a SPI-bootable image, run 'make da850_am18xxevm'. This will build
+the u-boot.ais file that needs to be written to SPI flash.
+
+
+Flashing the images to Nand
+===========================
+The AIS image can be written to SPI flash using the following commands.
+Assuming that the network is configured and enabled and the u-boot.ais file
+is tftp'able.
+
+U-Boot > sf probe 0
+U-Boot > sf erase 0 +320000
+U-Boot > tftp u-boot.ais
+U-Boot > sf write c0700000 0 $filesize
+
+
+Recovery
+========
+
+In the case of a "bricked" board, you need to use the TI tools found
+here[1] to write a UBL file and u-boot.bin. Once the system is running
+again from these tools a good u-boot.ais may be re-written to SPI flash.

This board, as far as I know (which isn't much) doesn't use NAND, just
SPI. The USE_NAND section of da850evm.h doesn't seem reachable today at
least.

But the title for above says 'Flashing the images to Nand' ? It should
be SPI.

da850_am18xxevm is for the Spectrum Digital EVM for the AM1808. For
the Logic PD board you will need 'make da850evm'. See [1]

This is a good idea.
But just to make it clear: Afaik the da850evm configuration works for
both the AM1808 and the OMAP-L138 board from LogicPD (at least I am
using it with the AM1808 experimenter's kit from LogicPD). The
da850_am18xxevm is for the Spectrum Digital board. At least this is
what I understood from the discussion with Manjunath Hadli in the in
the u-boot mailing list thread I cited earlier. I hope this is
correct, I haven't got other boards than the AM1808 board from LogicPD
to test.

AFAIK the difference between AM1808 and OMAP-L138 is that,
1: The AM1808 has EEPROM and stores the MAC address in it where as
OMAP-L138 stores the MAC address in SPI flash.
2: The revision number differs for both.

Are you sure? I don't see that in datasheets/schematics.

I don't think this is right. I believe on the Logic PD board it's
stored in SPI (I know mine isn't stored in EEPROM). I think the answer
is that the OMAP-L138 has DSP and the AM part does not. This would mean
that Logic PD gets the most re-use out of the base-board possible :)

This is funny since the Logic PD board is also called the "AM1808
Evaluation Module" rather than a "Davinci" EVM. So the README needs a
little more work :) I'll update and rename.

Takes the load function from arch/arm/lib/spl_nand.c instead. This will
allow for easier integration of SPL-boots-Linux code on other arches.
Kill off CONFIG_SPL_NAND_LOAD as a separate option.

OK, I was wrong, I will complain. :-)
The commit message didn't mention you were changing
CONFIG_SPL_NAND_SIMPLE. That needs to be able to support small SPLs.
Is your new "enhanced" nand_spl_load small enough (with proper
configuration) to work with all the SPLs that currently use
nand_spl/nand_boot.c (e.g. PPC 44x)?

OK, I suspect it would be close-to-fail. There's a "few" bytes overhead
to parse the header and so forth, but it also allows for direct Linux
booting. Is that something you want for these machines or no? It
wouldn't be hard to put the enhanced version nand_spl_simple.c and leave
nand_spl_load.c alone.

I don't think there's room for any new features at all. The SPL must
fit in 4K. Canyonlands is at 4020 bytes currently.
Why can't the new functionality be conditionally built?

nand_spl_simple.c is what I'm talking about needing to not expand. Why
does the new stuff need to be bound to a specific NAND boot implementation?

I'm not sure there would be a point. The nand_boot() method is read
u-boot.bin from nand, read env from nand and read redundant env from
nand, boot u-boot. The spl_nand_load_image method doesn't boot u-boot,
reads the image header, parses, reads the image. In short, I don't
think a modified version would gain us anything more than a lot of
complex #ifdefs :(

Sorry, I got it backwards. I mean (and did locally) leave the very tiny
and simple approach alone, add to the version where we have a little,
but not a lot, of space.
