* cppcheck cleanup: fix nullPointer errorsWolfgang Denk2014-11-072-0/+4
| | | | | | | | | | | There are a number of places where U-Boot intentionally and legally accesses physical address 0x0000, for example when installing exception vectors on systems where these are located in low memory. Add "cppcheck-suppress nullPointer" comments to silence cppcheck where this is intentional and legal. Signed-off-by: Wolfgang Denk <wd@denx.de>

* | arm: mxs: Add support for generating signed BootStreamMarek Vasut2014-04-042-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add serial console support into SPLMarek Vasut2014-04-011-1/+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: Adjust the load address of U-Boot and SPL for HABMarek Vasut2014-03-314-9/+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: mxs: Setup stack in JTAG modeMarek Vasut2013-10-171-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

* ARM: mxs: rename function that sets AUTO_RESTART flagHector Palacios2013-08-311-6/+3
| | | | | | | | | | | | | | | | | | The AUTO_RESTART flag of HW_RTC_PERSISTENT0 register will power up the chip automatically 180ms after power down. This bit must be enabled by the boot loader to ensure the target can start upon hardware reset or watchdog reset even when powered from a battery. Currently the function named 'mxs_power_clear_auto_restart()' is setting this flag although the 'clear' in its name suggest the opposite. This patch renames the function to 'mxs_power_set_auto_restart()' and removes the comment about EVK revision A which was confusing because the function indeed was setting the flag.

| | | | | | | | | | | | | | | | | | | | | | | Add mkimage support for generating and verifying MXS bootstream. The implementation here is mostly a glue code between MXSSB v0.4 and mkimage, but the long-term goal is to rectify this and merge MXSSB with mkimage more tightly. Once this code is properly in U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following headers are moved to a i.MX common location: - regs-common.h - regs-apbh.h - regs-bch.h - regs-gpmi.h - dma.h This way this header can be re-used also by other i.MX platforms. For example the i.MX6 which will need it for the upcoming NAND support.
