I’m doing some development on an AM335x ARM CPU and want to run
applications in the U-Boot command prompt. My problem: the code is much
slower in U-Boot than it is in Linux. I was wondering if U-Boot is able to
set clock settings and if there's a way that I can tweak them to improve
performance of

Currently the code in 'arch/arm/cpu/armv7/start.S' calls

from 'cpu_init_crit'. But 'cpu_init_cp15' is already using stack

I am using the core watchdog of the P2041 on the kmp204x board.
For the watchdog initialization I use the mpc85xx framework and
the powerpc register definitions. However, I had to modify both
for the following reasons (Patches 1 to 4):

I noticed a problem while testing Wolfgang's patch
PPC: fix "Warning: FOO uses hard float, BAR uses soft float".

seems to have issues in CPU POST test. I see similar problem
both with and also without Wolfgang's patch applied:

Yes, I am booting in internal mode, so that I can load U-Boot from NAND

Hello,
I am working on an i.MX25 board, and would like to know the recommended
mechanism for putting code in before the first instruction in the
executable, but outside the *_spl system.
Basically, the i.MX25 has a smart boot rom in the CPU, which will
extract the first block, and interpret it (as

Hi,
I want to know what is the instruction for sleeping in ARM Cortex A8.
I did execute a WFI instruction seems to be a NOP.
void cpu_idle()

unsigned long tmp = 0;

Dears,
I'm not able to find the code for Cortex A9, but
in some discussion I saw it is (maybe) planned
to be in cpu/cortex_a9.
Is this correct?
Anyway, can you possibly update me about the current status?
Thx,

Is your board really similar, i. e. did you copy all the CPLD stuff
from MPC5121ADS as well? Otherwise, ARIA might be a better choice to
copy code from.

I'm booting and running, after making a slight change to start.S to get

Hi Kim,
I recently tried calling the u-boot/cpu/mpc83xx/cpu.c : upmconfig function
to configure one of my UPMs to work as a Compact flash controller.
When I tried the compile I am getting the error from the #else of this code
void upmconfig (uint upm, uint *table, uint size)

Which CPU (ARCH) should i define for ARM7EJS ?
