Creating CMake project for STM32U5 divide memory

[nicolas]

I'm using STM32CubeIDE 1.18.1 and when i create a new STM32 CMake Project for a STM32U5, the generated ld file contain only half the memory.

For example here what is generated in STM32U575ZITXQ_FLASH.ld:

MEMORY
{
  RAM	(xrw)	: ORIGIN = 0x20040000,	LENGTH = 512K     /* Memory is divided. Actual start is 0x20000000 and actual length is 768K */
  SRAM4	(xrw)	: ORIGIN = 0x28000000,	LENGTH = 16K
  FLASH	(rx)	: ORIGIN = 0x08100000,	LENGTH = 1024K    /* Memory is divided. Actual start is 0x08000000 and actual length is 2048K */
}

This doesn't happens when creating a classic STM32 project.

I have also found differences in the startup file. Some IRQ handler doesn't have the same name (GPDMA1_ChannelX_IRQHandler vs GPDMA1_CHX_IRQHandler).
