| * | common: Rewrite hiding the end of memoryYork Sun2015-12-15-8/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the name may be confusing, the CONFIG_SYS_MEM_TOP_HIDE reserves some memory from the end of ram, tracked by gd->ram_size. It is not always the top of u-boot visible memory. Rewrite the macro with a weak function to provide flexibility for complex calcuation. Legacy use of this macro is still supported.

| * | Reserve secure memoryYork Sun2015-12-15-0/+15
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Secure memory is at the end of memory, separated and reserved from OS, tracked by gd->secure_ram. Secure memory can host MMU tables, security monitor, etc. This is different from PRAM used to reserve private memory. PRAM offers memory at the top of u-boot memory, not necessarily the real end of memory for systems with very large DDR. Using the end of memory simplifies MMU setup and avoid memory fragmentation. "bdinfo" command shows gd->secure_ram value if this memory is marked as secured. Signed-off-by: York Sun <yorksun@freescale.com>
* | spl: mmc: use block device number, not hard-coded 0Eric Nelson2015-12-14-3/+5
| | | | | | | | | | | | | | | | | | | | | | In order to support boot from multiple devices through board_boot_order, it's necessary to use the block number of a device. The use of a hard-coded 0 for the device number also creates a need to re-order block devices for use in SPL like this: http://git.denx.de/?p=u-boot.git;a=blob;f=board/freescale/mx6slevk/mx6slevk.c;hb=HEAD#l195 Signed-off-by: Eric Nelson <eric@nelint.com>
* | part: fix "part list ... -bootable varname" to use hexStephen Warren2015-12-13-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately U-Boot assumes that almost all numbers are in hex, including partition numbers passed to e.g. "load". So, the command "part list mmc 0 -bootable devplist" should use hex when writing partition numbers into $devplist, so they'll be correctly interpreted.

When using OF_BAD_ADDR as the return value of dev_get_addr(), it creates potential size mismatch as dev_get_addr() uses FDT_ADDR_T_NONE as the return value which can be either -1U or -1ULL depending on CONFIG_PHYS_64BIT.

| | | | | | | | | | | | | | | | | | | It is risky to have two different functions with much the same code. Future authors may update one but not the other. It is hard to see which parts are the same and which are different. Unify the functions and drop the differences that are not really needed. Note that one puts() becomes printf() as Tom mentioned that this does not affect image size: https://patchwork.ozlabs.org/patch/537276/ Note: It would be better to have an empty printf() and avoid the #ifdef for CONFIG_SPL_LIBCOMMON_SUPPORT.
