Installation on a MPC5200 based custom board
Hi all. I saw that someones trying to work on a custom board based on mpc5200. I have: * u-boot 1.2.0 * kernel 2.6.21 * arch=powerpc * custom dts based on lite5200b.dts * USB port (USB2) configured on the Ethernet port Is it necessary to combine Ethernet and usb nodes? However this is the log when a usb-storage is plugged: hub 1-0:1.0: state 7 ports 2 chg evt 0004 ppc-of-ohci f0001000.usb: GetStatus roothub.portstatus [1] = 0x00010101 CSC PPS CCS hub 1-0:1.0: port 2, status 0101, change 0001, 12 Mb/s hub 1-0:1.0: debounce: port 2: total 100ms stable 100ms status 0x101 ppc-of-ohci f0001000.usb: GetStatus roothub.portstatus [1] = 0x00100103 PRSC PPS PES CCS usb 1-2: new full speed USB device using ppc-of-ohci and address 2 BUG: soft lockup detected on CPU#0!

Re: R: Installation on a MPC5200 based custom board
Ok .

Case arch = powerpc
I saw that cdm is modified in two fields.
arch/powerpc/platforms/mpc52xx_common.c file, in function:

.
/* Use internal 48 Mhz */
out_8(cdm-ext_48mhz_en, 0x00);

if (in_be32(cdm-rstcfg) 0x40) /* Assumes 33Mhz clock */
out_be16(cdm-fd_counters, 0x0001);
else
out_be16(cdm-fd_counters, 0x);
.
and in file arch/powerpc/platforms/52xx/lite5200.c , function:
void __init lite5200_calibrate_decr(void)
{
ppc_tb_freq = 0x1F78A40; /* hardcoded default */
/* CPU FREQUENCY FORCED TO 396 MHz VALUE */
ppc_proc_freq = 0x179A7B00; /* hardcoded default */
..

The code is equal but obviously the path change

out_be16(cdm-fd_counters, 0x0001);
else
out_be16(cdm-fd_counters, 0x);
.
And in function: mpc52xx_calibrate_decr(void)
.
xlbfreq = __res.bi_busfreq;
/* if bootloader didn't pass bus frequencies, calculate them */
if (xlbfreq == 0) {
...
/* Compute all frequency from that CDM settings */
xlbfreq = (tbl_end - tbl_start) 8;
cpufreq = (xlbfreq * core_mult[in_be32(cdm-rstcfg)0x1f])/10;
ipbfreq = (in_8(cdm-ipb_clk_sel) 1) ?
