2013-03-27Exynos5: Fix errata 773022 and 774769 on Exynos52502013.02.3Alexander Graf
The exynos5250 chip is affected by the errata 773022 (disable loop buffer) 774769 (refrain streaming-write to ever allocate into the L2 cache) and needs to get the respective fixes as mentioned above applied. This is done in the Samsung downstream kernel within Linux. However, that approach fails to work when we run the guest kernel in HYP mode, as in now Linux's errata fixup code runs without privileges to access the aux control register. So instead, let's patch up u-boot (where CPU errata fixes belong to anyways), so that we can happily run a kernel. This fixes random segmentation faults on Arndale for me, that mostly occured because of the broken loop buffer. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-03-27vfat: Fix mkcksum argument sizesMarek Vasut
In case a function argument is known/fixed size array in C, the argument is still decoyed as pointer instead ( T f(U n[k]) ~= T fn(U *n) ) and therefore calling sizeof on the function argument will result in the size of the pointer, not the size of the array. The VFAT code contains such a bug, this patch fixes it.

2013-02-04arndale5250: Boot in Hyp mode and enable architected timersChristoffer Dall
First, to boot in Hyp mode we need to change to non-secure mode, which involves configuring the frequency of the arch. timers and setting all interrupts on the gic to group 1 (this code was inspired by the boot wrapper code). Second, signal the secondary CPU while still in secure mode and have the secondary CPU run the SPL. The SPL checks the hardware cpu id, and if it's a secondary CPU, it will initialize non-secure mode inside the SPL, enter Hyp mode, and finally enter a new SMP pen with the same poking stick interface as the regular kernel uses. Third, on CPU0 we wait until u-boot is fully up to actually enter the non-secure mode on CPU0, and stay in non-secure svc mode right up until we actually load the kernel, where the last thing we do is enter Hyp mode. Let it roll... Signed-off-by: Jeremy C. Andrus <jeremya@cs.columbia.edu> Signed-off-by: Christoffer Dall <cdall@cs.columbia.edu>

2012-12-06common: main: rework cmd timeout handlingRob Herring
The readline_from_buffer timeout functionality is broken in multiple ways. If CONFIG_CMDLINE_EDITING is not enabled, the timeout value was never used. If CONFIG_BOOT_RETRY_TIME is enabled, then that time is always used and the specified timeout has no effect. The same (or what should be the same) timeout code is duplicated in multiple places. The new behavior is this: The user specified timeout passed to readline_from_buffer is the timeout to get the 1st character. After that the endtime value is used if enabled. For example, if 20 seconds is passed in and the retry_time is 60 seconds, the user has 20 seconds to enter the first character and 60 seconds to complete the input.

2012-12-06pxe: localboot fixesRob Herring
Add support for value of -1 For localboot. A value of -1 means return to u-boot prompt. localboot value is often 0, so we need to distinguish the value from localboot being selected. A value of greater than or equal to 0 means attempt local boot command. If localboot is selected, we don't want to try other entries. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2012-12-06pxe: always display a menu when presentRob Herring
The prompt flag is for displaying a "boot:" prompt in pxelinux. This doesn't make sense for u-boot as we don't support the pxelinux command interface. So we should just ignore prompt statements and always show the menu if a menu is present. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
