Memory range capsule gives us a way to notify that some memory regions
should be left untouched across the next reset.
See UEFI specification, section 8.5.3.
Since how we should handle this kind of capsule is totally up to
the system, no implementation will be added in this commit.

Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.
In this commit, we will support capsule on disk mechanism.
Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

Since update_flash() is used only in update_tftp(), it should be
guarded with appropriate config options.
After the commit 3149e524fc, common/update.c will be built under
either CONFIG_UDATE_TFTP, CONFIG_DFU_TFTP or CONFIG_UPDATE_FIT.
Since CONFIG_UPDATE_FIT, hence fit_update(), doesn't rely on
update_flash(), the compiler may cause an "unused" warning if
CONFIG_UPDATE_FIT=y and CONFIG_UPDATE_TFTP=n and CONFIG_DFU_TFTP=n.
This is, for example, the case for sandbox defconfig where
EFI_CAPSULE_FIRMWARE_FIT is enabled for test purpose.

A previous commit is adding EFI_TCG2_PROTOCOL, which in it's eventlog

Let's add the necessary GUID so 'efidebug table' command can display

In the previous patches we only introduced a minimal subset of the
EFI_TCG2_PROTOCOL protocol implementing GetCapability().
So let's continue adding features to it, introducing the
GetEventLog() and HashLogExtendEvent() functions.
In order to do that we first need to construct the eventlog in memory,
specifically in EFI_BOOT_SERVICES_DATA memory and a configuration table
from EFI_ACPI_MEMORY_NVS.
U-Boot won't currently add any events to the log or measure any
components, but will expose the necessary EFI APIs for applications
to do so.

At present when more than one substitution is made this function
overwrites its buffers. Fix this bug and update the tests now that they
can pass.
Also update the debug code to show all substrings, since at present it

Signed-off-by: Simon Glass <sjg@chromium.org>
At present the 'nlen' variable increases with each loop. If the previous
loop had back references, then subsequent loops without back references
use the wrong value of nlen. The value is larger, meaning that the string
terminator from nbuf is copied along to the main buffer, thus terminating
the string prematurely.
This leads to the final result being truncated, e.g. missing the last
(unmatched) part of the string. So "match match tail" become
"replaced replaced" instead of "replaced replaced tail".
Fix this by resetting nlen to the correct value each time around the lop.

Add tests to check for buffer overflow using simple replacement as well
as back references. At present these don't fully pass.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present this function always allocates a large amount of stack, and
selects its own size for buffers. This makes it hard to test the code
for buffer overflow.
Separate out the inner logic of the substitution so that tests can call
this directly. This will allow checking that the algorithm does not
overflow the buffer.
Fix up one of the error lines at the same time, since it should be
printing nbuf_size, not data_size.

Add tests for the setexpr regex commands.
Note that these tests currently crash on sandbox due to an existing bug in
the setexpr implementation, so two of the tests are commented out.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present this function assumes that a size of 4 refers to a ulong. This
is true on 32-bit machines but not commonly on 64-bit machines.
This means that the 'l' specify does not work correctly with setexpr.
Add an explicit case for 32-bit values so that 64-bit machines can still
use the 'l' specifier. On 32-bit machines, 64-bit is still not supported.
This corrects the operation of the default size (which is 4 for setexpr),
so update the tests accordingly.
The original code for reading from memory was included in 47ab5ad145
("cmd_setexpr: allow memory addresses in expressions") but I am not adding
a Fixes: tag since that code was not written with 64-bit machines in mind.

This command currently has no tests. Add some for basic assignment and the

Note that the default size for setexpr is ulong, which varies depending on

default size is 64 bits.

- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:
```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
