You're welcome.

No, you don't need to program anything. The driver only uses he
Cypress BIOS programmed in ROM in the chip.
You just need to register a struct platform_device in your board code
with the base address, IRQ and port configuration - Something like:
#include <linux/usb/c67x00.h
..
static struct resource c67x00_resources[] = {
[0] = {
.start = 0x84000000,
.end = 0x8400000f,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = 3,
.end = 3,
.flags = IORESOURCE_IRQ,
},
};
static struct c67x00_platform_data c67x00_data = {
.sie_config = C67X00_SIE1_HOST | C67X00_SIE2_HOST,
.hpi_regstep = 0x02,
};
static struct platform_device c67x00 = {
.name = "c67x00",
.id = 0,
.num_resources = ARRAY_SIZE(c67x00_resources),
.resource = c67x00_resources,
.dev.platform_data = &c67x00_data,
};
