[U-Boot] Falcon Mode implemented version

[U-Boot] Falcon Mode implemented version

[Rajdeep Vaghasia]

Hi all,

I have the following queries.

1) Can anyone suggest me the exact version of u-boot in which falcon mode
is implemented?

I also wanted to know, if is there any readme available for that
implementation.

Please also tell me, "where exactly in the u-boot code" it is implemented.

2)  The u-boot version in which SPL for NOR flash is implemented.

If no such version is available, then please tell me about the patch in
which this SPL for NOR flash is implemented.

Thanks in advance.

Regards,
Rajdeep Vaghasia.

There is no exact version - falcon mode was merged more as one year ago.
Take simply 2013.07 or u-boot TOT.

There is no "exact the code" - to speed up the boot, several parts were
changed.

You can check for code surrounded by CONFIG_CMD_SPL and CONFIG_SPL_OS_BOOT.

There is at least a couple of boards supporting SPL and booting form
NOR: woodburn (MX35) and a3m071(MPC 5200).

Hi Stefano,
As in the case of NAND, u-boot_spl.bin is generated in u-boot/spl_nand/
directory,
In case of NOR, where exactly the separate spl image will be generated?
or
Will "u-boot.bin" contain the whole "spl + secondary u-boot"?
Please help me with these,

Thanks in advance,
Rajdeep Vaghasia

You're wrong: spl_nand is the old legacy spl. It is maintained for old
boards, but it should not be used for new projects.

Setting CONFIG_SPL, u-boot is generated into the spl/ directory. Please
try to compile the boards I have mentioned - you can then check how
production runs.

No, but there is an option to concatenate automatically SPL and u-boot
if desired.
