Re: [U-Boot] [PATCH 15/17] Add console command to access io space registers

Dear Simon Glass,

In message 1351902453-27956-16-git-send-email-sjg@chromium.org you wrote:

Provide u-boot console functions to access IO space registers. A no thrills implementation, accessing one register at a time.

For example: boot > iod 80 0080: 00000094 boot > iod.w 80 0080: 0094 boot > iod.b 80 0080: 94 boot > iow.b 0x80 12 boot > iod 0x80 0080: 00000012

What are the exact use cases where this is necessary, i. e. where plain md / mw does not work?

Best regards,

Wolfgang Denk
