Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

We currently expose host addresses in the EFI memory map. That can be
bad if we ever want to use sandbox to boot strap a real kernel, because
then the kernel would fetch its memory table from our host virtual address
map. But to make that use case work, we would need to have full control
over the address space the EFI application sees.
So let's expose only U-Boot addresses to the guest until we get to the
point of allocation. EFI's allocation functions are fun - they can take
U-Boot addresses as input values for hints and return host addresses as
allocation results through the same uint64_t * parameter. So we need to
be extra careful on what to pass in when.
With this patch I am successfully able to run the efi selftest suite as
well as grub.efi on aarch64.

Varargs differ between sysv and ms abi. On x86_64 we have to follow the ms
abi though, so we also need to make sure we use x86_64 varargs helpers.
This patch introduces generic efi vararg helpers that adhere to the
respective EFI ABI. That way we can deal with them properly from efi
loader code and properly interpret variable arguments.

We try hard to make sure that SMBIOS tables live in the lower 32bit.
However, when we can not find any space at all there, we should not
error out but instead just fall back to map them in the full address

This can for example happen on systems that do not have any RAM mapped
in the lower 32bits of address space. In that case having any SMBIOS
tables at all is better than having none.

The EFI image loader tries to determine which target architecture we're
working with to only load PE binaries that match.
So far this has worked based on CONFIG defines, because the target CPU
was always indicated by a config define. With sandbox however, this is
not longer true as all sandbox targets only encompass a single CONFIG
option and so we need to use compiler defines to determine the CPU
architecture.

Our nand_ecc_modes_t is already a bit abused by value NAND_ECC_SOFT_BCH.
This enum should store ECC mode only and putting algorithm details there
is a bad idea. It would result in too many values impossible to support

To solve this problem let's add a new enum. We'll have to modify all
drivers to set it properly but once it's done it'll be possible to drop
NAND_ECC_SOFT_BCH. That will result in a cleaner design and more
possibilities like setting ECC algorithm for hardware ECC mode.

The USBOH module on imx25 chips contains two USB controllers which are
called USB OTG Controller and USB Host Controller. Each one has its EHCI
root hub. The OTG Controller's EHCI registers start at offset 0, the Host
Controller's registers start at offset 0x400.
We set CONFIG_MXC_USB_PORT=0 to select the OTG Controller and 1 for the
Host Controller. Therefore, IMX_USB_PORT_OFFSET must be 0x400. Using
this setting, the Host Controller starts working on my imx25 board.
Please note that the imx25 reference manual claims that the Host
Controller's registers start at 0x200. This is not correct. The Linux

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.
The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.
