board/spear/common: move code to arch/arm/cpu/arm926ejs/spear/

2017-08-26T18:56:10+00:00

The code in board/spear/common/ is not board-specific but
SoC-specific. Therefore, boards from other vendors than "spear" may
want to re-use this code, which is currently difficult with the code
being placed in board/spear/common/.

Since this code really is SoC-specific, this commit moves it to
arch/arm/cpu/arm926ejs/spear/, with the rest of the SPEAr related
code.

env: Rename setenv() to env_set()

2017-08-16T12:22:18+00:00

We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.

board_f: Drop setup_dram_config() wrapper

2017-04-05T20:36:51+00:00

By making dram_init_banksize() return an error code we can drop the
wrapper. Adjust this and clean up all implementations.

SPEAr: Enable dcache for fast file transfer

2012-07-07T12:07:41+00:00

Enable data cache with 1:1 mapping of DDR to enable fast file
transfer over tty which was doing lot of copy.

This feature is enabled only for flashing operation i.e. when
CONFIG_SPEAR_USBTTY is enabled.

This has been tested on SPEAr320, SPEAr600 and SPEAr900 evaluation
boards.

Following figures show an estimate on the performance improvements. The
test setup was a Linux host (not Windows) and involved measurement of
only binary transfer time, through kermit. The flash erase and flash
copy time would be unaffected by these patches.

Another thing is this that the timings remained more or less same across
ARM9 and Cortex based devices, hence reporting only one of the cases.

SPEAr: Initialize SNOR in early_board_init_f

2012-07-07T12:07:41+00:00

flash reading is required earlier than flash_init is called since the env_init
is called before flash_init. This makes the smi_init necessary before env_init
being called.

SPEAr: Place ethaddr write and read within CONFIG_CMD_NET

2012-07-07T12:07:40+00:00

ethaddr can be optionally read from i2c memory. So, chip_config command supports
reading/writing hw mac id into i2c memory. Placing this code within
CONFIG_CMD_NET as this would only be needed when network interface is configured

SPEAr: Eliminate dependency on Xloader table

2012-07-07T12:07:40+00:00

Xloader table was used primarily to inform u-boot about the DDR size. However,
now the ddr size is calculated at runtime which eliminates any need for the
Xloader table. So removing this unnecessary code.
