71c52dba2b Add trace support to generic board
Add hooks for tracing to generic board, including:

- allow early tracing to start early as possible in U-Boot
- reserve memory for trace buffer
- copy early trace buffer to main trace buffer after relocation
- setup full tracing support after relocation

a0ba279ac6 generic_board: reduce the redundancy of gd_t struct members
This commit refactors common/board_f.c and common/board_r.c
in order to delete the dest_addr and dest_addr_sp from
gd_t struct.

As mentioned as follows in include/asm-generic/global_data.h,

  /* TODO: is this the same as relocaddr, or something else? */
  unsigned long dest_addr;        /* Post-relocation address of U-Boot */

dest_addr is the same as relocaddr.
Likewise, dest_addr_sp is the same as start_addr_sp.

It seemed dest_addr/dest_addr_sp was used only as a scratch variable
to calculate relocaddr/start_addr_sp, respectively.

With a little refactoring, we can delete dest_addr and dest_addr_sp.

b5bec88434 Use 'unsigned int' for global_data's baudrate
We decided to used unsigned int here, rather than unsigned long. But
for the generic global_data it is still unsigned long. So change it
over.

1938f4a5b6 Introduce generic pre-relocation board_f.c
This file handles common pre-relocation init for boards which use
the generic framework.

It starts up the console, DRAM, performs relocation and then jumps
to post-relocation init.

50b1fa3996 Add generic global_data
Add a generic global_data structure which all archs will eventually
use.
