Split and fix the total SRAM size for STM32L47x/L48x/L49x/L4Ax device. Those MCUs with up to 320 Kbytes SRAM: • 96 Kbytes SRAM1 and 32 Kbyte SRAM2 on STM32L47x/L48x. • 256 Kbyte SRAM1 and 64 Kbyte SRAM2 on STM32L49x/L4Ax The sram0 node at address 0x20000000 and sram1 at address 0x10000000 Signed-off-by: Francois Ramu <[email protected]>

Adding the definition for the stm32L4plus devices Note that SRAM3 address differs from 0x2003000 on stm32L4P5x/L4Q5x and 0x2004000 on stm32L4R5x/L4S5x |

Split and fix the total SRAM size for STM32L4Px/L4Qx/L4Rx/L4Sx device. Those MCUs with up to 640 Kbytes SRAM: This is 640KB for the STM32L4Rxxx and STM32L4Sxxx devices : • 192 Kbytes SRAM1 + 64 Kbytes SRAM2 + 384 Kbytes SRAM3 This is 320KB for the STM32L4P5xx and STM32L4Q5xx devices : • 128 Kbytes SRAM1 + 64 Kbytes SRAM2 + 128 Kbytes SRAM3 Signed-off-by: Francois Ramu <[email protected]>
