/* The LPC4088 has 512Kb of FLASH beginning at address 0x0000:0000 and
 * 96Kb of total SRAM: 64Kb of SRAM in the CPU block beginning at address
 * 0x10000000 and 32Kb of Peripheral SRAM in two banks, 8Kb at addresses
 * 0x20000000 bank0 first and 8kb at 0x20002000 at bank0 second. And 16Kb
 * at 0x20004000 on bank1.
 *
 * Here we assume that .data and .bss will all fit into the 64Kb CPU SRAM
 * address range.
