[U-Boot] [Question] bardrate both in gd_t and bd_t

Hi.

I notice bardrate parameter bd_t as well as gd_t.

In include/asm-generic/global_data.h

typedef struct global_data { bd_t *bd; unsigned long flags; unsigned int baudrate;

We have "baudrate" here.

E.g. arch/arm/include/asm/u-boot.h

typedef struct bd_info { unsigned int bi_baudrate; /* serial console baudrate */

We have "bi_baudrate".

My question is what's the difference between gd->baudrate and bd->bi_baudrate. Why do we need both?

Since baudrate is a common paramter for all architectures, bd->bi_baudrate looks weird to me.
