IMD provides support for small and large allocations. Region IMD Small memory is 1 KB with 32 Bytes alignment, this region holds smaller entries without having to reserve a whole 4 KB page. Remaining space is assigned to IMD Large to hold various regions with 4 KB alignment. The UCSI kernel (kernel version 4.19) driver maps the UCSI_ACPI memory as not cached. Cache mapping is set on page boundaries and all IMD Small is within the same page. If another driver maps the memory as write-back before the UCSI driver is loaded then the UCSI driver will fail to map the memory as not cached. Placing UCSI_ACPI in IMD Large region will prevent this mapping issue since it will now be located within its own page. This patch will force UCSI_ACPI region to be located in IMD Large region.
