* arm: mxs: Add serial console support into SPLMarek Vasut2014-04-01-1/+14
| | | | | | | | | | | | | | | Add support for serial console into the i.MX23/i.MX28 SPL. A full, uncrippled serial console support comes very helpful when debugging various spectacular hardware bringup issues early in the process. Because we do not use SPL framework, but have our own minimalistic SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not use preloader_console_init(), but instead use a similar function to start the console. Nonetheless, to avoid blowing up the size of the SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT is defined, which is disabled by default.

* arm: mxs: Add support for generating signed BootStreamMarek Vasut2014-03-31-0/+87
| | | | | | | | | | | | | | | | | | | | | | | This patch adds the groundwork for generating signed BootStream, which can be used by the HAB library in i.MX28. We are adding a new target, u-boot-signed.sb , since the process for generating regular non-signed BootStream is much easier. Moreover, the signed bootstream depends on external _proprietary_ _binary-only_ tool from Freescale called 'cst', which is available only under NDA. To make things even uglier, the CST or HAB mandates a kind-of circular dependency. The problem is, unlike the regular IVT, which is generated by mxsimage, the IVT for signed boot must be generated by hand here due to special demands of the CST. The U-Boot binary (or SPL binary) and IVT are then signed by the CST as a one block. But here is the problem. The size of the entire image (U-Boot, IVT, CST blocks) must be appended at the end of IVT. But the size of the entire image is not known until the CST has finished signing the U-Boot and IVT. We solve this by expecting the CST block to be always 3904B (which it is in case two files, U-Boot and the hand-made IVT, are signed in the CST block).

* arm: mxs: Adjust the load address of U-Boot and SPL for HABMarek Vasut2014-03-31-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | When using HAB, there are additional special requirements on the placement of U-Boot and the U-Boot SPL in memory. To fullfill these, this patch moves the U-Boot binary a little further from the begining of the DRAM, so the HAB CST and IVT can be placed in front of the U-Boot binary. This is necessary, since both the U-Boot and the IVT must be contained in single CST signature. To make things worse, the IVT must be concatenated with one more entry at it's end, that is the length of the entire CST signature, IVT and U-Boot binary in memory. By placing the blocks in this order -- CST, IVT, U-Boot, we can easily align them all and then produce the length field as needed. As for the SPL, on i.MX23/i.MX28, the SPL size is limited to 32 KiB, thus we place the IVT at 0x8000 offset, CST right past IVT and claim the size is correct. The HAB library accepts this setup. Finally, to make sure the vectoring in SPL still works even after moving the SPL from 0x0 to 0x1000, we add a small function which copies the vectoring code and tables to 0x0. This is fine, since the vectoring code is position independent. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de>
* ARM: AM43xx: Change DDR3 Reset ValueDave Gerlach2014-03-04-1/+1
| | | | | | | | | The bit DDR3_RST_DEF_VAL inside CTRL_DDR_IO represents the default value of the ddr reset value for DDR3 before the EMIF takes over.

* ARM: AM43xx: EMIF: configure self-refresh entry delayDave Gerlach2014-03-04-2/+2
| | | | | | | | | | Per a suggestion from the hardware team, program the emif_pwr_mgmt_ctrl and emif_pwr_mgmt_ctrl_shdw registers within the EMIF to hold the desired delay in cycles that the EMIF waits without an access to enter self-refresh, in this case 8192 cycles. With this, code desiring to enter self refresh only has to toggle one bit to enable it. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>

| * arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini2014-02-26-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
