I had a look to
"<koen> booting improved when enabling the CONFIG_OMAP_MUX, but that kills ehci"
from yesterdays IRC [1].
Koen: Can you please try to delete the line
MUX_CFG_34XX("AA8_3430_USB2HS_TLL_CLK", 0x5f0,
OMAP34XX_MUX_MODE6 | OMAP34XX_PIN_OUTPUT)
in file arch/arm/mach-omap2/mux.c and check if ehci is still broken if you enable CONFIG_OMAP_MUX?
Looking to HW manual [2] at
Figure 34. Host USB Port Design
and uboot pin mux
MUX_VAL(CP(ETK_D10_ES2), (IDIS | PTU | EN | M4)) /*GPIO_24*/
#define CONTROL_PADCONF_ETK_D10_ES2 0x05F0
at Beagle 0x05F0 has to be configured for GPIO and not HSUSB2_TLL as kernel pin mux does.
If this works for you, we have to check which kernel pin mux config is correct for beagle and which causes the boot improvement.
Cheers
Dirk
