omap4 boot rom api

[Alexander Shishkin]

Hi,

I was wondering if there are any plans to make the boot rom api documentation
public (or at least some bits of it)? Why I ask is that I would like to
implement booting over usb (to x-loader or barebox or whatever) without
having to implement drivers for omap i2c, twl, musb and a gadget, especially
so that boot rom already implements that.

Thanks,

Hi,

[ It seems that it didn't make it to the list yesterday because I wasn't
subscribed, thus resending. ]

I was wondering if there are any plans to make the boot rom api documentation
public (or at least some bits of it)? Why I ask is that I would like to
implement booting over usb (to x-loader or barebox or whatever) without
having to implement drivers for omap i2c, twl, musb and a gadget, especially
so that boot rom already implements that.

So, if it's possible to provide at least usb-related bits, that would be
great.

TIA,

I think Alexander is looking at 27.5 Services for HLOS Support - the ROM
Code service routines listed there are those of immediate need for cp15
control, but there may be additional services which may help in
solutions such as [1].

Well, they did get the romapi vector base wrong, but thankfully it's
also in the TRM.
I assume earlier ESes of 4430 had it slightly differently and then
noone bothered to
port omapflash to new ones.

That I hear is correct ES2 has slightly different ones compared to ES1

Jay,
is there any plans for putting the omapflash source code public for
OMAP4 with changes for latest ES revs?

Hi,

   Although the omapflash project provides lots information about the bootrom api,

but I could not find I2C related bootrom APIs definitions. Does anybody know the

function prototype of the I2C related bootrom APIs?
