| * | | malloc_f: enable SYS_MALLOC_F by default if DM is onMasahiro Yamada2015-03-28-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This option has a bool type, not hex. Fix it and enable it if CONFIG_DM is on because Driver Model always requires malloc memory. Devices are scanned twice, before/after relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc memory before relocation. As it is board-independent, handle it globally.

* | | | ARM: move -march=* and -mtune= options to arch/arm/MakefileMasahiro Yamada2015-03-27-69/+32

By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.

| | | | | | | | | | | | | | | | | | | | | | | | The L2 cache is used as a temporary SRAM on SPL. Now the secondary CPUs store the necessary code for jumping to Linux on their L1 I-caches. So, the L2 cache can be disabled much earlier, at the very entry of U-Boot proper (lowlevel_init). This makes the boot sequence clearer. Also, as the L1 cache has been disabled by the start.S, enable_caches() does not need to do it again. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
