SPEAr: Enable dcache for fast file transfer

2012-07-07T12:07:41Z

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

2012-07-07T12:07:41Z

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. Signed-off-by: Amit Virdi Acked-by: Stefan Roese Signed-off-by: Stefan Roese

SPEAr: Add configuration options for spear3xx and spear6xx boards

2012-07-07T12:07:40Z

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. Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi Signed-off-by: Stefan Roese

SPEAr: Add interface information in initialization

2012-07-07T12:07:40Z

Few Designware peripheral registers need to be modified based on the ethernet interface selected by the board. This patch supports interface information in ethernet driver Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi Signed-off-by: Stefan Roese

SPEAr: Add macb driver support for spear310 and spear320

2012-07-07T12:07:40Z

SPEAr310 and SPEAr320 SoCs have an extra ethernet controller. The driver for this device is already supported by u-boot, so configuring board configuration file and defining base addresses etc to make use of the common driver Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi Signed-off-by: Stefan Roese

SPEAr: Place ethaddr write and read within CONFIG_CMD_NET

2012-07-07T12:07:40Z

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 Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi Signed-off-by: Stefan Roese

SPEAr: Eliminate dependency on Xloader table

2012-07-07T12:07:40Z

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. Signed-off-by: Amit Virdi Acked-by: Stefan Roese Signed-off-by: Stefan Roese

SPEAr: Fix ARM relocation support

2012-07-07T12:07:39Z

While the u-boot code is running from the flash, it is essential that no access is made to the bss segment. This is due to the fact that .rel.dyn and .bss areas overlap and former contains information used in relocation. In SPEAr, this was not taken into consideration. As a result, while the relocation wasn't complete, dram_init populated an uninitialized global variable resulting in corruption of .rel.dyn area, which resulted in u-boot crash. This commit fixes this problem by removing code that accesses bss segment Signed-off-by: Amit Virdi Acked-by: Stefan Roese Signed-off-by: Stefan Roese
