To: u-boot
some rockchip soc will not include lib/timer.c in SPL stage,
so implement timer driver for some soc can use us delay function in SPL.

Changes in v1: None
Changes in v2:
- add udelay function
Changes in v3:
- fix some coding style
Changes in v4: None

should probably use 'uint64_t' for 'tick' and the return value, and
use 'unsigned int' for 'usec'

you mean use u32, i think unsigned int is the same with u32

it is correspond to TRM register name, and it can easy to find
register in TRM.

From: Lin Huang @ 2015-11-10 10:24 UTC (permalink / raw)
To: u-boot
since different rockchip SOC have different size of SRAM,
So the size SYS_MALLOC_F_LEN may different, so move this
config to rk3288 own Kconfig

some soc(rk3036 etc) use dw_mmc but do not have internal dma,
so we implement fifo mode to read and write data.

This looks too long to me. Can you first add a patch to move
everything inside the 'if (data)' block to a separate static function?
> + /* only fifo mode need it */
> + if (data->flags == MMC_DATA_READ && host->fifo_mode) {
I think both of these blocks should be in the same 'if (host->fifo_mode)'
In fact, can it be 'if (host->fifo_mode && size)' ?

rk3036 mmc do not have internal dma, so we use fifo mode when read
and write data, we get the fifo mode and fifo depth property from
dts, pass to dw_mmc driver.

I think this should be a separate patch as it does not relate to your
commit message.
Also can you use fdtdec_get_bool() instead?

Acked-by: Simon Glass <sjg@chromium.org>
But can you please add a TODO(email) somewhere to convert this to use
the ns16550 driver when possible? It supports DEBUG_UART which is the
standard way of implementing this. See debug_uart.h for definitions of
printch(), etc.
We can worry about it later, as I understand it will need a little
extra work, but it should be possible to use the same driver code. The
problem currently is that you want to include only the debug UART
portion of the serial driver, not the serial driver itself. That seems
like a generally useful feature for very constrained devices.
Also please see nit below.

Please add a comment that we cannot fit the code to access the device
tree in SPL for this chip (due to SRAM size limits), so these are
hard-coded here.

Can it be:

From: Lin Huang @ 2015-11-10 10:24 UTC (permalink / raw)
To: u-boot
rk3036 only 4K size SRAM for SPL, so only support
timer, uart, sdram driver in SPL stage, when finish
initial sdram, back to bootrom.And in rk3036 sdmmc and
debug uart use same iomux, so if you want to boot from
sdmmc, you must disable debug uart.
Signed-off-by: Lin Huang <hl@rock-chips.com>
---
Changes in v1:
- clean copyright announcement
Changes in v2:
- support SPL
Changes in v3:
- delete DEBUG_UART config
- modify ENV_MEM_LAYOUT_SETTINGS config
Changes in v4:
- delete some unuse config advice by Sjoerd Simons
Changes in v5:
- use CONFIG_DWMMC

What is a tag? This should be more descriptive with more detail. E.g.
the tag is a 4-byte header at the start of the image. It is required
by the boot ROM...

Is the initial loader the 'SPL' image, or is it more than that? I am
not keen on the name INIT, since it could mean anything. So if it
means SPL, can we use that name? Also please add more detail to the
help: exactly how is it limited? Does the loader need to be the same
size as SRAM, or at most xx bytes smaller.

The Rockchip boot ROM could load & run an initial spl loader,
and continue to load a second level boot-loader(which stored
right after the initial loader) when it returns.
Modify idblock generation code to support it.

I've done one more pass through. The MMC patch needs a small refactor
I think and I've made comments on a few other paches. There are also
some warnings as below - not all are real, but please take a look and
fix what you can.
$ patman -nmt

Unless there is anything else that comes up, I'm hoping that this
needs only one more revision, and then I'll pick up the series.

I've pushed an update to u-boot-rockchip/testing. If you have time,
please give it a try. I'll push it to master soon.

sorry,
missing header is caused by too large SPL image. header is available
if SPL size is fine.
same issue can happen on current master branch too, so this is not the
problem of u-boot-rockchip/testing.
please ignore for merging.

I suspect this is unrelated to the 3036 bringup, but at the moment i
can't build the 3288 firefly SPL smaller then 32k :( (iotw small enoug
to be used as an SD card image). The image ends up being about 250
bytes too big..
Playing silly games with nm, it seems the big items are the sdram
bringup-code, mmc core/drivers and ofcourse (vs)printf related
functions (followed by a long tail of smaller things).
Seems like a bit of dieting is required ;)

Did you try using the new tiny-printf implementation
(CONFIG_USE_TINY_PRINTF)? It should save you ~2.5KiB.

Thanks for the tip, a first quick tried unfortunately shows that both
the gpio uclass and the mmc core support fail to build when that option
is enabled (missing?sprintf, and various _strtoXX functiosn).
Probably worth a try in fixing that though given the pontential
savings.

Ah, right. This new option has not been enabled on a SPL-DM
platform yet. Something might be missing there.

Yes, this should hopefully not be too hard to fix.
Thanks,

Yes. Maybe some #ifdefs for each subsystem in rk3288_pinctrl_request()
would help.
But in general it is too close to the limit. With the bug-fixed gcc it
is fine, but we are stuck with the bug for a while.
Would be great if we could move to tiny printf(). Adding sprintf()
requires refactoring but should be doable.

Simon

ooi do you have a reference to that gcc bug ? :)

Yeah, though it didn't seem to hard to get rid of the sprintf usage in
the calling code either.. ?
