| * | imx_common: check for bmode Serial DownloaderStefan Agner2017-01-27-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before commit 81c4eccb55cc ("imx: mx6: fix USB bmode to use reserved value") a non-reserved value has been used to trigger Serial Downloader using bmode, which translated to a GPR9 value of 0x10. However, on some boards the non-reserved value lead to unreliable bmode command. With the above mentioned commit, U-boot switched to use [7:4] b0001, which translates to GPR9 0x10 for Serial Downloader mode. Check for the new value and classify it as Serial Downloader mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function image_create_config_parse_oneline is pretty complex, and since more parameters will be added to support secure booting, we refactor the function to make it more readable. Also, when a line contained just a keyword without any parameters, strtok_r returned NULL, which was then indiscriminately fed into atoi, causing a segfault. To correct this, we add a NULL check before feeding the extracted token to atoi, and print an error message in case the token is NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable secure boot, we need to jump back into the BootROM to continue the SoC's boot process instead of letting the SPL load and run the main U-Boot image. But, since the u-boot-spl.img (including the 64 byte header) is loaded by the SoC as the main image, we need to compensate for the header length to get a correct entry point. Thus, we subtract the header size from the destination address, so that the execution address points at the actual entry point of the image. The current boards ignore both parameters anyway, so this change shouldn't concern them.

The signature is added at the tail of the second stage loader (= SPL in U-boot terminology). The size of the second stage loader was 64KB, and it was consistent across SoCs. The situation changed when LD20 SoC appeared; it loads 80KB second stage loader, and it is the only exception. Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is loaded from the 64KB offset of non-volatile devices. This means the signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot proper image. Let's move the U-Boot proper image to 128KB offset. It uses 48KB for nothing but padding, and we could actually locate the U-Boot proper at 80KB offset. However, the power of 2 generally seems a better choice for the offset address.

It is platform-dependent how to detect the memory banks. Currently, UniPhier adopts the memory banks _alleged_ by DT. This is based on the assumption that users bind a correct DT in their build process. Come to think of it, the DRAM controller has already been set up before U-Boot is entered (because U-Boot runs on DRAM). So, the DRAM controller setup register seems a more reliable source of any information about DRAM stuff. The DRAM banks are initialized by preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever), so this means the source of the reliability is shifted from Device Tree to such early-stage firmware. However, if the DRAM controller is wrongly configured, the system will crash. If your system is running, the DRAM setup register is very likely to provide the correct DRAM mapping. Decode the SG_MEMCONF register to get the available DRAM banks. The dram_init() and dram_init_banksize() need similar decoding. It would be nice if dram_init_banksize() could reuse the outcome of dram_init(), but global variables are unavailable at this stage because the .bss section is available only after the relocation. As a result, SG_MEMCONF must be checked twice, but a new helper uniphier_memconf_decode() will help to avoid code duplication. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
