* arm: spl: For Falcon Mode, set a default machid of ~0Tom Rini2013-08-15-1/+6
| | | | | | | | | | | | With device trees, boards do not always set CONFIG_MACH_TYPE now, so we must not rely on this define being set. The kernel uses ~0 to see if we have a valid machine number or not, so set that as the default, invalid machine, id and only fix if CONFIG_MACH_TYPE is set.

* arm: Add CONFIG_DELAY_ENVIRONMENT to delay environment loadingSimon Glass2013-01-10-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | This option delays loading of the environment until later, so that only the default environment will be available to U-Boot. This can address the security risk of untrusted data being used during boot. Any time you load untrusted data you expose yourself to a bug in the code. The attacker gets to choose the data so can sometimes carefully craft it to exploit a bug. We try to avoid touching user-controlled data during a verified boot unless strictly necessary. Since the default environment is good enough in this case (or you would just change it), this gets around the problem by just not loading the environment. When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a run-time way of enabling loading of the environment. Add this to the fdt as /config/delay-environment.

So if there are any dirty cache lines before disabling the L2 cache these will be synchronized with the main memory when invalidate_dcache_all() runs in the last part of U-boot The two functions after flush_dcache_all is using the stack. So this data will be on the cache. After disable when invalidate is called the data will be flushed from cache to memory. This corrupts the stack in invalida_dcache_all.
