dm: Add base driver model support

2014-03-04T17:15:29+00:00

Add driver model functionality for generic board.

This includes data structures and base code for registering devices and
uclasses (groups of devices with the same purpose, e.g. all I2C ports will
be in the same uclass).

The feature is enabled with CONFIG_DM.

Introduce common timer functions

2013-11-04T16:06:16+00:00

Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:

CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down

All functions are weak or ifdef'ed so they can still be overriden by any
platform.

i2c: add i2c_core and prepare for new multibus support

2013-07-23T03:54:28+00:00

This Patch introduce the new i2c_core file, which holds
the I2C core functions, for the rework of the multibus/
multiadapter support.
Also adds changes in i2c.h for the new I2C multibus/multiadapter
support. This new support can be activated with the
CONFIG_SYS_I2C define.

Add trace support to generic board

2013-06-26T14:16:41+00:00

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

generic_board: reduce the redundancy of gd_t struct members

2013-06-07T18:17:01+00:00

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.

Use 'unsigned int' for global_data's baudrate

2013-03-15T20:14:02+00:00

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.

Introduce generic pre-relocation board_f.c

2013-03-15T20:13:59+00:00

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.

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