efi_loader: Handle memory overflows

2016-04-18T21:11:44+00:00

jetson-tk1 has 2 GB of RAM at 0x80000000, causing gd->ram_top to be zero.
Handle this by either avoiding ram_top or by using the same type as
ram_top to reverse the overflow effect.

gunzip.c: use block layer for writes

2016-04-18T21:11:41+00:00

Call blk_dwrite to ensure that the block cache is notified
if enabled and remove build breakage when CONFIG_BLK is enabled.

efi_loader: Expose ascending efi memory map

2016-04-18T21:11:40+00:00

The EFI memory map does not need to be in a strict order, but 32bit
grub2 does expect it to be ascending. If it's not, it may try to
allocate memory inside the U-Boot data memory region.

We already sort the memory map in descending order, so let's just
reverse it when we pass it to a payload.

efi_loader: Always flush in cache line size granularity

2016-04-18T21:11:39+00:00

The cache line flush helpers only work properly when they get aligned
start and end addresses. Round our flush range to cache line size. It's
safe because we're guaranteed to flush within a single page which has the
same cache attributes.

efi_loader: Increase path string to 32 characters

2016-04-18T21:11:37+00:00

Whenever we want to tell our payload about a path, we limit ourselves
to a reasonable amount of characters. So far we only passed in device
names - exceeding 16 chars was unlikely there.

However by now we also pass real file path information, so let's increase
the limit to 32 characters. That way common paths like "boot/efi/bootaa64.efi"
fit just fine.

efi_loader: Add el torito support

2016-04-18T21:11:36+00:00

When loading an el torito image, uEFI exposes said image as a raw
block device to the payload.

Let's do the same by creating new block devices with added offsets for
the respective el torito partitions.

efi_loader: Split drive add into function

2016-04-18T21:11:35+00:00

The snippet of code to add a drive to our drive list needs to
get called from 2 places in the future. Split it into a separate
function.

lib/crc8: Add crc start value

2016-04-12T00:48:26+00:00

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.

I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

efi_loader: Always allocate the highest available address

2016-04-01T21:18:06+00:00

Some EFI applications (grub2) expect that an allocation always returns
the highest available memory address for the given size.

Without this, we may run into situations where the initrd gets allocated
at a lower address than the kernel.

This patch fixes booting in such situations for me.
