The ECDSA peripheral before ECO5 of esp32h2 does not perform the ECDSA
sign operation in constant time. This allows an attacker to read the
power signature of the ECDSA sign operation and then calculate the
ECDSA key stored inside the eFuse. The commit adds a countermeasure
for this attack. In this case the real ECDSA sign operation is
masked under dummy ECDSA sign operations to hide its real power
signature
This commit adds/updates the USB PHY related HAL APIs. The following changes
are made:
- Updated 'usb_wrap_hal.h' API
- Added 'usb_serial_jtag_hal.h' API
- Added LL cap macros to distinguish feature differences between the LLs of
different targets:
- '..._LL_EXT_PHY_SUPPORTED' indicates whether the USB WRAP/USJ supports
routing to an external FSLS PHY.
- Tidied up some RCC LL functions and their callers.
- Added 'usb_wrap_types.h' and 'usb_serial_jtag_types.h' to provide types used
in LLs.
- Fixed some spelling/naming issues as part of code-spell pre-commit
For targets that only contain a USJ peripheral (and not a DWC OTG), their
'usb_fsls_phy_ll.h' headers only contain a single function
('usb_fsls_phy_ll_int_jtag_enable()') whose feature is already covered by
functions in 'usb_serial_jtag_ll.h'. Thus, this header is redundant.
This commit does the following:
- Remove 'usb_fsls_phy_ll.h' for targets that only contain a USJ peripheral
- Rename 'usb_fsls_phy_[hal|ll].[h|c]' to `usb_wrap_[hal|ll].[h|c]` for targets
that contain a DWC OTG peripheral. This better reflects the underlying peripheral
that the LL header accesses.
This commit updates the HCD API to allow port resets to occur even if pipes
are allocated. The pipes cannot be active and the port reset will simply
restore the pipes (by reinitializing their channel registers) following the
reset.
Changes:
- Allow port resets while channels are allocated
- Remove pipe persistance API 'hcd_pipe_set_persist_reset()'
This commit renames USB PHY related HAL files from "usb_phy_xxx" to
"usb_fsls_phy_xxx" since they are only designed to support Full-Speed/Low-Speed
Serial USB PHYs. This renmaing is done to accommodate future USB PHYs that use
other PHY interfaces (e.g., UTMI, ULPI etc).
This commit updates the "*_struct.h" files for the USB OTG peripheral:
- Added/removed some missing/non-existing register fields
- Added "reserved" place holders for registers that are missing due to IP
configuration.
- Added "usb_dwc_cfg.h" listing the USB OTG IP configuration for each target.
- Updated LL/HAL according to register field updates. Also tidied up the include
directives in those headers.
