cmd: kaslrseed: add command to generate value from hwrng

2021-12-24T02:54:56+00:00

Allow the kaslr-seed value in the chosen node to be set from a hardware
rng source.

Tested on a Rockchip PX30 (Odroid Go Advance), you must have loaded
the devicetree first and prepared it for editing. On my device the
workflow goes as follows:

setenv dtb_loadaddr "0x01f00000"
load mmc 0:1 ${dtb_loadaddr} rk3326-odroid-go2.dtb
fdt addr ${dtb_loadaddr}
fdt resize
kaslrseed

and the output can be seen here:
fdt print /chosen
chosen {
        kaslr-seed = <0x6f61df74 0x6f7b996c>;
        stdout-path = "serial2:115200n8";
};

tpm: use more algorithms than sha256 on pcr_read

2021-11-30T08:23:49+00:00

The current tpm2_pcr_read is hardcoded using SHA256. Make the
actual command to TPM configurable to use wider range of algorithms.
The current command line is kept as is i.e limited to SHA-256 only.

pxe: Allow calling the pxe_get logic directly

2021-11-12T00:02:43+00:00

Refactor this code so that we can call the 'pxe get' command without going
through the command-line interpreter. This makes it easier to get the
information we need, without going through environment variables.

pxe: Refactor sysboot to have one helper

2021-11-12T00:02:39+00:00

The only difference between the three helpers is the filesystem type.
Factor this out and call the filesystem functions directly, instead of
through the command-line interpreter. This allows the file size to be
obtained directly, instead of via an environment variable.

We cannot do the same thing with PXE's tftpboot since there is no API
at present to obtain information about the file that was read. So there
is no point in changing pxe_getfile_func to use a ulong for the address,
for example.

This is as far as the refactoring can go for the present.

pxe: Return the file size from the getfile() function

2021-11-12T00:02:36+00:00

It is pretty strange that the pxe code uses the 'filesize' environment
variable find the size of a file it has just read.

Partly this is because it uses the command-line interpreter to parse its
request to load the file.

As a first step towards unwinding this, return it directly from the
getfile() function. This makes the code a bit longer, for now, but will be
cleaned up in future patches.

pxe: Clean up the use of bootfile

2021-11-12T00:02:28+00:00

The 'bootfile' environment variable is read in the bowels of pxe_util to
provide a directory to which all loaded files are relative.

This is not obvious from the API to PXE and it is strange to make the
caller set an environment variable rather than pass this as a parameter.

The code is also convoluted, which this feature implemented by
get_bootfile_path().

Update the API to improve this. Unfortunately this means that
pxe_setup_ctx() can fail, so add error checking.

Move the header file into the main include/ directory so we can use it
from the bootmethod code. Move the C file into boot/ since it relates to
booting.
