arm: spear: Fix booting - relocate vector table to 0 (low-vector)

2015-08-28T16:33:16Z

Booting SPEAr600 eval board doesn't work with current mainline U-Boot. With this patch the low-vector bit is left to '0'. Resulting in the common relocation of the vectors to 0 (SDRAM) to work correctly. Tested on the SPEAr600 EVB. Signed-off-by: Stefan Roese Acked-by: Viresh Kumar Cc: Vipin Kumar

kbuild: add dummy obj-y to create built-in.o

2014-02-19T16:07:50Z

We are going to switch over to Kbuild in upcoming commits. Each makefile must have non-empty obj- or obj-y to generate built-in.o on Kbuild. Signed-off-by: Masahiro Yamada

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: 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
