Re: [U-Boot] [PATCH] arm: add 8-byte alignment for ABI compliance before board_init_f

Dear Reinhard Meyer,

Is bootflag ever used? If not, why not change the parameter to give the gd address to board_init_f?

No, bootflag is never used and could / should be removed.

Passing gd as parameter makes no sense, thoug, as it's global data and we reserve a register to store it's address, so it can always be used with minimal overhead.

One further thought, why not init the reserved register in assembly and remove the gd relevant code in C? But that bears some risk if the register is changed and the assembly is forgotten to adapt..

We try to do as much as pssible in C, and only what really cannot be avoided in assembly.

Best regards,
