pytest.ini enables log_cli, so logging the full ninja stdout after a
failed first-time build is one multi-MB ERROR. That hung shard 3/6 for
hours after the hints test. Log the last 80 lines; keep the full output
on the exception and at DEBUG.
idf.py mcp-server printed startup, shutdown, and error messages on
stdout. On the stdio MCP transport, stdout is the JSON-RPC channel, so
those non-JSON lines can confuse or break strict clients. Route them to
stderr like the other diagnostics in mcp_ext.py.

idf.py mcp-server tool handlers were spawning idf.py without redirecting
stdin, so the child inherited the long-lived MCP JSON-RPC transport and
could hang indefinitely on tools/call. Pass stdin=subprocess.DEVNULL on
every spawn of idf.py.

Trim bootloader size by moving some logs to DEBUG. Allows
compiling bootloader on P4 with CONFIG_ESPTOOLPY_FLASHMODE_QIO
without changing partition table offset
Add a new CMake function esp_partition_flash_binary() that provides a
unified API for registering partition data binaries to be flashed. It
replaces the direct esptool_py_flash_target calls scattered across
components (spiffs, fatfs, nvs_flash) with a single function that:
- Resolves partition offset from the partition table automatically
- Determines encryption requirements (auto-detect or ALWAYS_PLAINTEXT)
- Creates per-partition flash targets (e.g. idf.py <partition>-flash)
- Optionally includes the binary in `idf.py flash` via FLASH_IN_PROJECT
On the linux target, the function registers binaries for pre-loading
into the emulated flash. A build-time manifest (linux_flash_data.txt)
is generated via file(GENERATE), and partition_linux.c reads it at
runtime to copy each binary into the memory-mapped flash buffer at
the correct offset.
The partition_ops example is updated to use the new function and
includes a custom_partition with pre-built data to demonstrate the
full workflow, including on the linux target.
Wire esp_blockdev, comp_a, and comp_b into the test app dependency graph
so ioctl def files are registered and the POST_BUILD overlap checker runs.

FastMCP was renamed to MCPServer in mcp 2.0, which made idf.py mcp-server
report a false "MCP dependencies not available" error. Prefer MCPServer
and keep a FastMCP fallback for mcp 1.x.

Add an OPTIONAL flag to idf_component_include so callers can ask
"include this component if it exists" without aborting the build
when the component is unknown.
Without OPTIONAL, the function behaves exactly as before -- it
calls __get_component_interface_or_die and the build aborts on a
miss. With OPTIONAL, the function performs a non-fatal interface
lookup and returns silently if the component is not known. When
combined with INTERFACE <variable>, the variable is set to the
empty string on miss and to the component's interface target on
hit, so callers can write:
idf_component_include(button OPTIONAL INTERFACE button_iface)
if(button_iface)
target_sources(${COMPONENT_TARGET} PRIVATE button_glue.c)
target_link_libraries(${COMPONENT_TARGET} PRIVATE ${button_iface})
endif()
This gives consumers a public, non-fatal way to wire up integrations
with components that may or may not be in the build (managed
dependencies pulled in only by some board configurations, optional
feature glue, etc.) without reaching into the private
__get_component_interface helper or doing dual-namespace
COMPONENTS_DISCOVERED checks against both <name> and <ns>__<name>
forms.
Backward compatible: existing call sites do not pass OPTIONAL and
continue to fail loudly on miss.

Validate linked RISC-V executables when
CONFIG_COMPILER_ENABLE_RISCV_ZCMP is enabled on affected chips.
Disassemble each function and reject mstatus.MIE clears that lack an
earlier mintthresh write of 0xff.
Handle csrrci, csrrw, and register-mask csrrc patterns while ignoring
csrrs. Add build-only coverage for valid and invalid sequences with
CMake v1 and v2.
Stop the hardware stack guard before switching stacks during restart,
and keep ZCMP disabled for TEE test apps that still require the
workaround.
Use a non-deprecated bootloader support API in the mock build test.
Keep the test focused on validating the generated bootloader support mock.

Add ESP_KEY_SOURCE_BUFFER and ESP_KEY_SOURCE_PSA key sources so all
hardware backends (DS, ECDSA, secure element) are accessed via PSA
key IDs through a single esp_tls_cfg_t.client_key field.

The spiram-xip IROM/DROM alignment tests assumed the XIP region always
leaves an alignment gap before the next MMU page: they executed into the
gap and expected an instruction access fault followed by a register dump.
When the section ends exactly on an MMU page boundary there is no gap - the
device prints "<IROM/DROM> alignment gap not added into heap" and returns,
the framework restarts cleanly (esp_restart_noos, no panic), and the test
timed out waiting for a register dump.
