* fastboot: add support for continue commandRob Herring2014-12-18-0/+4
| | | | | | | | | | | | The fastboot continue command is defined to exit fastboot and continue autoboot. This commit implements the continue command and the exiting of fastboot only. Subsequent u-boot commands can be processed after exiting fastboot. Autoboot should implement a boot script such as "fastboot; mmc read <...>; bootm" to fully implement the fastboot continue function.

| * mmc: Fix handling of bus widths and DDR card capabilitiesAndrew Gabbasov2014-12-12-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask, it is never cleared, even if switching to DDR mode fails, and if the controller driver uses this flag to check the DDR mode, it can take incorrect actions. Also, DDR related checks in mmc_startup() incorrectly handle the case when the host controller does not support some bus widths (e.g. can't support 8 bits), since the host_caps is checked for DDR bit, but not bus width bits. This fix clearly separates using of card_caps bitmask, having there the flags for the capabilities, that the card can support, and actual operation mode, described outside of card_caps (i.e. bus_width and ddr_mode fields in mmc structure). Separate host controller drivers may need to be updated to use the actual flags. Respectively, the capabilities checks in mmc_startup are made more correct and clear. Also, some clean up is made with errors handling and code syntax layout. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>

|/ | | | | | | | | | | The concept of a 'current bus' is now implemented in the command line rather than in the uclass. Also the address length does not need to be specified with each command - really we should consider dropping this from most commands but it works OK for now.

| * common: spl: Add interactive DDR debugger support for SPL imageAlison Wang2014-12-05-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support interactive DDR debugger, cli_simple.o, cli.o, cli_readline.o, command.o, s_record.o, xyzModem.o and cmd_disk.o are all needed for drivers/ddr/fsl/interactive.c. In current common/Makefile, the above .o files are only produced when CONFIG_SPL_BUILD is disabled. For LS102xA, interactive DDR debugger is needed in SD/NAND boot too, and I enabled CONFIG_FSL_DDR_INTERACTIVE. But according to the current common/Makfile, all the above .o files are not produced in SPL part because CONFIG_SPL_BUILD is enabled in SPL part, the following error will be shown, drivers/ddr/fsl/built-in.o: In function `fsl_ddr_interactive': /home/wangh/layerscape/u-boot/drivers/ddr/fsl/interactive.c:1871: undefined reference to `cli_readline_into_buffer' /home/wangh/layerscape/u-boot/drivers/ddr/fsl/interactive.c:1873: undefined reference to `cli_simple_parse_line' make[1]: *** [spl/u-boot-spl] Error 1 make: *** [spl/u-boot-spl] Error 2 So this patch fixed this issue and the above .o files will be produced no matter CONFIG_SPL_BUILD is enabled or disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The boot commands - bootz/bootm mandate a third argument which is the address to the FDT blob. In cases where this argument is not specified, boot fails with a message indicating a missing FDT. This causes non-FDT kernels to fail to boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 709ea54 made a subtle change to the way the U-Boot API jump table is set up. So at present putc(), getc(), tstc() and puts() do not work correctly from functions that use the U-Boot API. Previously these were set to the stdio functions, but these now take a parameter specifying which stdio device to use. Instead, we should change them to use the global functions which do not have a parameter. This is a slight change in behaviour. The functions will now output to all selected stdio devices - for example putc() will output a character to all devices selected by stdout. However in most cases there is only one, and it isn't necessarily incorrect behaviour anyway. The API version is not changed since it is compatible with what was there before.

It provides a simple buffer with an incrementing pointer. At present the implementation is inside dlmalloc. Move it into its own file so that it is easier to find. Rather than using relocation as a signal that the full malloc() is available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the simple malloc() should no longer be used. In some cases, such as SPL, even the code space used by the full malloc() is wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple malloc. In this case the full malloc is not available at all. It saves about 1KB of code space and about 0.5KB of data on Thumb 2.
