It is not necessary for bootpg to be present at text + 512KB.
With increase of u-boot size (768KB), bootpg section's address
cannot be fixed.

Hi All,

I just want to share my concern with respect to this patch.
This patch removed hard-coded value for 0x80000 and use 
CONFIG_SYS_MONITOR_LEN.

There were many Freescale boards config which don't have correct 
CONFIG_SYS_MONITOR_LEN(due to size increase from 512KB to 768KB). I 
fixed them in subsequent patch.

This linker file is being used by many other powerpc boards/platforms. 
Because of hard-coded value of 0x80000 in linker file, there boards are 
booting till now.
but after this patch,  there is a possibility there boards may not boot 
because of wrong value defined for CONFIG_SYS_MONITOR_LEN by board 
maintainers.

I will request powerpc board maintainers to check config file for 
correct value of CONFIG_SYS_MONITOR_LEN.

Regards,
Prabhakar

Dear Wolfgang,

With this patch I removed hard-coding(0x80000) present in 
arch/powerpc/cpu/mpc85xx/u-boot-nand.lds with CONFIG_SYS_MONITOR_LEN.
I also updated Freescale boards with correct CONFIG_SYS_MONITOR_LEN in 
subsequent patch.

There is a possibility of other powerpc boards to have incorrect 
CONFIG_SYS_MONITOR_LEN.
As I am not aware of actual size of the binary. May I update 
CONFIG_SYS_MONITOR_LEN for all powerpc platforms as 0x80000 or leave it 
up to the platform user to update with correct binary size.  I will 
check the build of these updated boards.

Thanks,
Prabhakar
