Revert "fdtdec: Use CONFIG_IS_ENABLED in board_fdt_blob_setup()"

2021-02-15T15:06:23+00:00

On Rockchip platforms we need this area of code in TPL, but there is no
TPL_SEPARATE_BSS symbol.

This reverts commit 0a2aaab0b678fd1778ff2fc59d0770fc82995532.

efi_loader: fix get_last_capsule()

2021-02-14T09:34:15+00:00

fix get_last_capsule() leads to writes beyond the stack allocated buffer.
This was indicated when enabling the stack protector.

utf16_utf8_strcpy() only stops copying when reaching '\0'. The current
invocation always writes beyond the end of value[].

The output length of utf16_utf8_strcpy() may be longer than the number of
UTF-16 tokens. E.g has "CapsuleКиев" has 11 UTF-16 tokens but 15 UTF-8
tokens. Hence, using utf16_utf8_strcpy() without checking the input may
lead to further writes beyond value[].

The current invocation of strict_strtoul() reads beyond the end of value[].

A non-hexadecimal value after "Capsule" (e.g. "CapsuleZZZZ") must result in
an error. We cat catch this by checking the return value of strict_strtoul().

A value that is too short after "Capsule" (e.g. "Capsule0") must result in
an error. We must check the string length of value[].

efi_loader: '.' and '..' are directories

2021-02-14T09:34:15+00:00

'.' and '..' are directories. So when looking for capsule files it is
sufficient to check that the attribute EFI_FILE_DIRECTORY is not set. We
don't have to check for these special names.

efi_loader: don't load beyond VirtualSize

2021-02-14T09:34:15+00:00

PE section table entries' SizeOfRawData must be a multiple of
FileAlignment, and thus may be rounded up and larger than their
VirtualSize.

We should not load beyond the VirtualSize, which is "the total size of
the section when loaded into memory" -- we may clobber real data at the
target in some other section, since we load sections in reverse order
and sections are usually laid out sequentially.

smbios: Allow a few values to come from sysinfo

2021-02-06T11:20:36+00:00

While static configuration is useful it cannot cover every case. Sometimes
board revisions are encoded in resistor straps and must be read at
runtime.

The easiest way to provide this information is via sysinfo, since the
board can then provide a driver to read whatever is needed.

Add some standard sysinfo options for this, and use them to obtain the
required information.

smbios: Add more options for the BIOS version string

2021-02-06T11:20:27+00:00

At present the version string is obtained from PLAIN_VERSION. Some boards
may want to configure this using the device tree, since the build system
can more easily insert things there after U-Boot itself is built. Add this
option to the code.

Also in some cases the version needs to be generated programmatically,
such as when it is stored elsewhere in the ROM and must be read first.
To handle this, keep a pointer around so that it can be updated later.
This works by storing the last string in the context, since it is easier
than passing out a little-used extra parameter.

Provide a function to update the version string.

smbios: Track the end of the string table

2021-02-06T11:20:23+00:00

Add a new member to the context struct which tracks the end of the string
table. This allows us to avoid recalculating this at the end.

smbios: Drop the eos parameter

2021-02-06T11:18:41+00:00

We can store this in the context and avoid passing it to each function.
This makes it easier to follow and will also allow keeping track of the
end of the string table (in future patches).

Add an 'eos' field to the context and create a function to set it up.

smbios: Use a struct to keep track of context

2021-02-06T11:18:41+00:00

At present we pass the ofnode to each function. We also pass the 'eos'
pointer for adding new strings. We don't track the current end of the
string table, so have smbios_string_table_len() to find that.

The code can be made more efficient if it keeps information in a
context struct. This also makes it easier to add more features.

As a first step, switch the ofnode parameter to be a context pointer.
Update smbios_add_prop() at the same time to avoid changing the same
lines of code in consecutive patches.
