2014-03-04dm: Add base driver model supportSimon Glass
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.

2013-11-04Introduce common timer functionsRob Herring
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.

2013-07-23i2c: add i2c_core and prepare for new multibus supportHeiko Schocher
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.

2013-06-26Add trace support to generic boardSimon Glass
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 Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-07generic_board: reduce the redundancy of gd_t struct membersMasahiro Yamada
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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Simon Glass <sjg@chromium.org>
2013-03-15Use 'unsigned int' for global_data's baudrateSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-15Introduce generic pre-relocation board_f.cSimon Glass
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.
