PATCH v2 2/24 SPEAr: Eliminate dependency on Xloader table

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.

PATCH v2 3/24 SPEAr: Place ethaddr write and read within CONFIG_CMD_NET

From: Vipin KUMAR <[email protected]>

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

PATCH v2 8/24 SPEAr: Add configuration options for spear3xx and spear6xx boards

From: Vipin KUMAR <[email protected]>

This patch adds options for all the below mentioned configurations and subsequently renames the include/configs/spearxxx.h files to spear3xx_evb.h, spear6xx_evb.h etc to depict evaluation board configuration.

SPEAr3xx and SPEAr6xx boards can be compiled in following configurations
1. Environment placed in NAND
2. Console on usb device
3. Console on usb device with environment placed in NAND
4. SPEAr310 and SPEAr320 support environment variables in parallel NOR flash.

From: Vipin KUMAR <[email protected]>

This patch modifies the default environment variables as:
1. Default bootargs:

- For environment present in NOR flash
root=/dev/mtdblock3
- For environment present in NAND flash
root=/dev/mtdblock7
- Removes "mem=" option
2. Introduces CONFIG_EXTRA_ENV_USBTTY as default usbtty env var even when usbtty is not selected
3. Add default definitions for nfsboot and ramboot
4. Add a new default environment variable(CONFIG_EXTRA_ENV_UNLOCK) for SPEAr310 and SPEAr320

Signifacance of CONFIG_EXTRA_ENV_USBTTY:
This environment variable is important for flashing utility to work. So if somebody accidently erases the env sector then also this variable must be preserved so that flashing utility functions properly.

Signifacance of CONFIG_EXTRA_ENV_UNLOCK:
This env variable is read by the cfi driver to unlock all flash sectors. This is necessary because the Parallel NOR flash connected on the spear310 and spear320 boards, M28W64, has all its sectors in locked state at reset and these have to be unlocked explicitly before being erased or written.

PATCH v2 11/24 SPEAr: Initialize SNOR in early_board_init_f

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.

On a beagleboard it's acting like the buffer isn't being flushed at first. If I type 'help' after switching from UART I have to hit space a few times to see all the output.

PATCH v2 14/24 SPEAr: Enable autoneg for ethernet

From: Shiraz Hashim <[email protected]>

Enabling autoneg avoids situation on few phys with fixed configuration. For example, in one situation, nfs boot timed out when phy configuration is 100Mbps. In another situtation, when traffic is directed to SPEAr, either thru cross-cable or thru switch, the TFTP or DHCP command in u-boot starts to timeout very often.

When Autoneg is ON, same phys started working perfectly.

PATCH v2 15/24 SPEAr: Enable dcache for fast file transfer

From: Shiraz Hashim <[email protected]>

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.

From: Vipin Kumar <[email protected]>

This patch enables flash protection(lock/unlock) for CFI devices. This is necessary because the Parallel NOR flash connected on the spear boards, M28W64, can be locked/unlocked on a sector basis. Moreover, all its sectors are in locked state at reset and these have to be unlocked explicitly before being erased or written.

PATCH v2 23/24 cleanup/SPEAr: Remove unnecessary parenthesis

In SPEAr configuration files, unnecessary paranthesis are used in some \#defines. Remove them as they serve no purpose

PATCH v2 24/24 cleanup/SPEAr: Define configuration flags more elegantly

In SPEAr, some of the configuration flags eg. CONFIG_SPEAR_EMI, were given value "1", which isn't required. Define the flags without assigning any value
