2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-13board_f: Rename initdram() to dram_init()Simon Glass
This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-05board_f: Drop return value from initdram()Simon Glass
At present we cannot use this function as an init sequence call without a wrapper, since it returns the RAM size. Adjust it to set the RAM size in global_data instead, and return 0 on success. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2017-04-05board_f: Drop board_type parameter from initdram()Simon Glass
It looks like only cm5200 and tqm8xx use this feature, so we don't really need it in generic code. Drop it and have the users access gd->board_type directly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>

2016-06-03board/freescale: Use unified setup_ddr_tlbs for spl boot and non-spl bootShengzhou Liu
We should use unified setup_ddr_tlbs() for spl boot and non-spl boot to make sure 'M' bit is set for DDR TLB to maintain cache coherence. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
2016-01-19Add more SPDX-License-Identifier tagsTom Rini
In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini <trini@konsulko.com>
2014-04-22powerpc/T4QDS: add two stage boot of nand/sdShaohui Xie
Add support of 2 stage NAND/SD boot loader using SPL framework. PBL initialise the internal SRAM and copy SPL, this further initialise DDR using SPD and environment and copy u-boot from NAND/SD to DDR, finally SPL transfer control to u-boot. NOR uses CS1 instead of CS2 when NAND boot, fix it. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

Add emulator support for T4240. Emulator has limited peripherals and interfaces. Difference between emulator and T4240QDS includes: ECC for DDR is disabled due the procedure to load images No board FPGA (QIXIS) NOR flash has 32-bit port for higher loading speed IFC and I2C timing don't really matter, so set them fast No ethernet Signed-off-by: York Sun <yorksun@freescale.com>
2013-05-14powerpc/t4240qds: Update DDR timing tableYork Sun
Update the timing table to support more rank density, based on the theory that similar density DIMMs have similar clock adjust and write level start timing. Update the timing for 1600 and 1866 MT/s. Tested with Micron MT18JSF1G72AZ-1G9E1 DIMMs, iDIMM M3CN-4GMJ3C0C-M92. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
