[U-Boot] [PATCH] hwconfig: Move HWCONFIG_BUFFER_SIZE into hwconfig.h

Before proper environment is setup, we extract hwconfig and put it into a buffer with size HWCONFIG_BUFFER_SIZE. We need to enlarge the buffer to accommodate longer string. Since this macro is used in multiple files, we move it into hwconfig.h.

1. I don't think HWCONFIG_BUFFER_SIZE should be getting set in include/hwconfig.h, this is unique to FSL 8xxx usage not to hwconfig 2. if you are doing to something like this it should be:
#ifndef CONFIG_HWCONFIG_BUFFER_SIZE #define CONFIG_HWCONFIG_BUFFER_SIZE 128 #endif
This allowing a board port to set it as needed.

If no one else uses this feature, I can move it to arch/powerpc/include/asm/config.h. How about that?

This is a good idea. Will do.

I cannot see in which way arch/powerpc/include/asm/config.h would be more FSL 8xxx specific ?

I can put it within
#if defined(CONFIG_MPC85xx) || \ defined(CONFIG_MPC83xx) || \ defined(CONFIG_MPC86xx) #ednif
How about that?
