Re: [U-Boot] [PATCH v2 16/17] Move low level eNET board init into dedicated sections

[Wolfgang Denk]

Dear Graeme Russ,

In message 1251195588-7799-1-git-send-email-graeme.r...@gmail.com you wrote:
 This patch is in readiness for moving all u-boot code + data from Flash to
 RAM. Low level init code is not needed after bootstrap and therefore does
 not need to be copied. Moving this code into dedicated sections makes it
 easier

But is this worth the effort? It makes the design more complicated.


Best regards,

Wolfgang Denk

In a business, marketroids, salespukes, and  lawyers  have  different
goals from those who actually do work and produce something. Usually,
is  is the former who triumph over the latter, due to the simple rule
that those who print the money make the rules.

Actually I think the opposite is true - The low level asm code is all
placed at the bottom (or is it top?) end of the Boot Flash rather than
interleaved in the rest of the .text section. This is critical for the
real mode code as there is a tight limit on the jump lengths. This patch
makes it all the more consistent
