reset_boot_mode Settings
By using the non-boot mode reset initialization mode the user can change the internal register addresses from base 1800_0000 to base
1900_0000, as required. The RC32334 reset-boot mode initialization setting values and mode descriptions are listed below.
pci_host_mode Settings
During reset initialization, the RC32334’s PCI interface can be set to the Satellite or Host mode settings. When set to the Host mode, the CPU must
configure the RC32334’s PCI configuration registers, including the read-only registers. If the RC32334’s PCI is in the PCI-boot mode Satellite mode,
read-only configuration registers are loaded by the serial EEPROM.
mem_addr[19:18]
9:8 MSB (9)
Boot-Prom Width specifies the memory port
width of the memory space which contains
the boot prom.

PCI-boot mode (pci_host_mode must be in satellite mode)
RC32334 will reset either from a cold reset or from a PCI
reset. Boot code is provided via PCI.
