* The Boot ROM bootloader loads only the first 32KBytes of U-Boot image from the external 16-bit NOR flash. We make U-Boot load the remaining contents of the image. * Put all function and data used for bootstrapping in the beginning of the U-Boot image in sections `.lpc18xx_image_top_text` and `.lpc18xx_image_top_data`. * Configure the boot pins to determine the boot source if the relevant fields in the One-Time Programmable memory are not set. * Configure the remaining EMC pins before reading the whole U-Boot image. The Boot ROM bootloader forgets to configure some EMC pins. * Reload the U-Boot image from NOR flash only when boot source is `EMC 16-bit`.
