See Documentation/admin-guide/kernel-parameters.txt

[KNL,ACPI] Mark specific memory as reserved.
Region of memory to be reserved is from ss to ss+nn.
Example: Exclude memory from 0x18690000-0x1869ffff
Some bootloaders may need an escape character
before '$',
like Grub2, otherwise '$' and the following number
will be eaten.
