In-Reply-To: Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi, I may be want to try to put U-Boot with a Embedded Linux on a custom MPC860 (33Mhz) board of course with Network (10 Mbps) ( 2MB ROM, 8 ou 16 MB of Flash, 4 MB of DRAM for the system, 16 MB of SRAM for the application ) So for U-Boot and Linux, I want to allow only the DRAM and a part of the flash ( example : 8 MB ) Is it possible to have U-Boot and the kernel linux in the prom without decompress the kernel in RAM ? Flash will be ok for the filesystem and my application. The SRAM should be use for my application Data Base. Is it enought with network support ?

Of course that is a _very_ _simple_ system. You should calculate with 512KB-1MB.
