8Status:
9   version v1.10.4
10
11Purpose:
12   ST Microelectronics official MCU package for STM32L1 series.
13
14Description:
15   This package is an extract of official STM32CubeL1 package written by ST Microelectronics.
16   It is composed of STM32Cube hardware abstraction layer (HAL) and low layer (LL) plus a set
17   of CMSIS headers files, one for each SoC in STM32L1 series.

19Dependencies:
20    None.

39    *ext/hal/st/stm32cube/stm32l1xx: rename SVC_IRQn -> SVCall_IRQn
40
41     SVCall_IRQn is used as enum value for SV Call Interrupt for Cortex-M
42     based SoCs for which CPU_CORTEX_M_HAS_BASEPRI=y. However stm32cube
43     for stm32l1xx uses SVC_IRQn enum value for this purpose.
44     This leads to this error:
45
46       arch/arm/include/cortex_m/exc.h:101:19: error: 'SVCall_IRQn'
47         undeclared (first use in this function); did you mean 'SVC_IRQn'?
48
49         NVIC_SetPriority(SVCall_IRQn, _EXC_SVC_PRIO);
50                          ^~~~~~~~~~~
51                          SVC_IRQn
52
53     NB: ext/hal/st/stm32cube/stm32l1xx/soc/stm32l151xb.h file was already
54     fixed in 9f8260457b86 ('ext: hal: st: stm32cube: Add HAL for
55     the STM32L1x series').

80   *Disable i2c HAL
81     Due to conflict with zephyr i2c.h (I2C_SPEED_STANDARD and I2C_SPEED_FAST
82     redefinition), deactivate STM32Cube I2C HAL. This raises no issue since
83     LL API is currently used for stm32 I2C driver.

86    ST Bug tracker ID: NA. Not a stm32cube issue

88   *stm32l151xb: add missing SPI_CR2_FRF definitions
89
90    The higher density parts correctly included the SPI_CR2_FRF definitions,
91    but these were missing for the low/medium density parts.  Without these
92    definitions, the zephyr SPI driver cannot be used on these parts.
