Hi Jagan,
Just have a quick question here.
After dropping non-DM code, for SPL use non-DM code should switch to SPL_DM and
use SPL OF CONTROL?
Here are the options, that we dealt based on the size constraints
1) try to use DM_SPL with SPL OF_CONTROL
Not possible
2) try PLATDATA
Adds extra bloat to SPLs which are already borderline, so not possible.
3) try TPL for truly small size
How would that help ? I don't need extra level of bootloader, I can use
SPL right now.
Exactly my thoughts too. I have a at91 based board (smartweb) in mainline
where the SPL fits into 4k sram ... no chance for 1) or 2) ...
I see the reasons for integrating more and more stuff into SPL, but
it should be possible to build a small SPL ...
Hopefully TPL stays really small ...
Hmm.. while writting (did not actually looked into TPL ...):
Is it possible to boot U-boot directly from TPL ?
if none works, we can see the other option. may be some glue code to
read flash for SPL or something else.
I'll have to take a look at the Renesas Gen2, but probably next year.
I talk with customers to get time for converting, but this also may
take some time ...
bye,
Heiko
