That's where the ugly mess pops up - RedBoot uses another
(incompatible) bd_t definition than U-boot, E.G:
typedef struct bd_info {
unsigned int bi_tag; /* Should be 0x42444944 "BDID" */
unsigned int bi_size; /* Size of this structure */
unsigned int bi_revision; /* revision of this structure */
unsigned int bi_bdate; /* bootstrap date, i.e. 0x11061997 */
unsigned int bi_memstart; /* Memory start address */
unsigned int bi_memsize; /* Memory (end) size in bytes */
unsigned int bi_intfreq; /* Internal Freq, in Hz */
unsigned int bi_busfreq; /* Bus Freq, in Hz */
unsigned int bi_cpmfreq; /* CPM Freq, in Hz */
unsigned int bi_brgfreq; /* BRG Freq, in Hz */
unsigned int bi_vco; /* VCO Out from PLL */
unsigned int bi_pci_freq; /* PCI Freq, in Hz */
unsigned int bi_baudrate; /* Default console baud rate */
unsigned int bi_immr; /* IMMR when called from boot rom */
unsigned char bi_enetaddr[6];
unsigned int bi_flashbase; /* Physical address of FLASH memory */
unsigned int bi_flashsize; /* Length of FLASH memory */
int bi_flashwidth; /* Width (8,16,32,64) */
unsigned char *bi_cmdline; /* Pointer to command line */
} bd_t;
I should probably migrate to U-boot anyway, but still ..
