From 377e367a8558c5327c925387ecf1f0a4ee7ca177 Mon Sep 17 00:00:00 2001 From: Stefano Babic Date: Wed, 26 Jun 2013 23:50:06 +0200 Subject: tools: dynamically allocate imx_header in imximage Change to dynamically allocate the imx_header to correctly allocate the IVT, Boot Data and DCD at correct locations depending on the boot media. Also check that the Image Vector Table Offset + IVT + Boot Data + DCD <= Initial Load Region Size. Previously struct imx_header was always 4096 bytes and was not dealing correctly with the Image Vector Table Offset. Now, the memory allocation looks for e.g. SD boot like this Storage u-boot.imx RAM Device 00000000 177ff000 <-------------- | 00000400 00000000 d1 00 20 40 IVT.header 177ff400 <------- | 00000404 00000004 00 00 80 17 IVT.entry 177ff404 ----------- | 00000408 00000008 00 00 00 00 IVT.reserved1 177ff408 | | | 0000040C 0000000C 2c f4 7f 17 IVT.dcd 177ff40C ------ | | | 00000410 00000010 20 f4 7f 17 IVT.boot 177ff410 ---- | | | | 00000414 00000014 00 f4 7f 17 IVT.self 177ff414 -------- | | 00000418 00000018 00 00 00 00 IVT.csf 177ff418 | | | | 0000041C 0000001C 00 00 00 00 IVT.reserved2 177ff41C | | | | 00000420 00000020 00 f0 7f 17 BootData.start 177ff420 <--- | | --- 00000424 00000024 00 60 03 00 BootData.length 177ff424 | | 00000428 00000028 00 00 00 00 BootData.plugin 177ff428 | | 0000042C 0000002C d2 03 30 40 DCD.header 177ff42C <----- | ... | 00001000 00000c00 13 00 00 ea U-Boot Start 17800000 <---------- While at it also remove the unused #define HEADER_OFFSET.
