PATCH 1/1 m28evk: Use GENERATED_GBL_DATA_SIZE

Quoted 3 lines

Use GENERATED_GBL_DATA_SIZE for calculating CONFIG_SYS_INIT_SP_OFFSET.

Maybe I'd be better to consolidate the i.MX28 config to a common config file and have only board specific stuff in the board-specific configs, which would in turn include the file?

Sounds like a good idea.

But this issue is not strictly related only to MX28. The same is for any SOC in u-boot, and most of CONFIG_ are duplicated in the configuration files for boards having the same SOC.

At the moment, we do this only for slightly different boards (imx27lite and magnesium, for example) or for boards having the same SOM.

Agree we can rationalize better, but it should be discussed if we plan to introduce some hierarchy in the configuration files - the board configuration file can include a SOC configuration file, that can include a ARCH configuration file....

Apart of that, I think it is not bad to merge this Fabio's patch - it makes the board consistent with the other ones.

Best regards,
Stefano Babic

Fine by me, but I can't test it.

Applied to u-boot-imx, thanks.

Dear Fabio Estevam,

I think this patch is wrong ... did I ack this one?

This 0x2000 is wrong, it should be 0x0. Otherwise your maths below overflow and SP is located at 0x21f80.
