Hi,
I'm trying to cross-compile Linux 2.6.33 for Freescale MPC5554 [1][2]. This
microcontroller is based on the e200z6 core. I could build the cross-development
tools, but I could miss something because I get an error message when building
Linux for PowerPC e200 core. Here are the steps I used:
$ tar xjvRf binutils-2.20.tar.bz2
$ mkdir binutils-build
$ cd binutils-build
$ ../binutils-2.20/configure --target=powerpc-linux-gnuspe --prefix=/home/nmarci/usr/local
$ make
$ make install
$ cd ..
$ export PATH=$PATH:/home/nmarci/usr/local/binutils/bin
$ tar xjvRf gcc-core-4.4.2.tar.bz2
$ mkdir gcc-build
$ cd gcc-build
$ ../gcc-4.4.2/configure --target=powerpc-linux-gnuspe --prefix=/home/nmarci/usr/local --disable-shared --disable-threads --enable-languages=c
$ make all-gcc
$ make install-gcc
$ cd ..
$ tar xjvRf linux-2.6.33.tar.bz2
$ ln -s linux-2.6.33 linux
$ cd linux
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnuspe- menuconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnuspe- vmlinux

Error: unrecognized option -me200
make[2]: *** [scripts/mod/empty.o] Error 2
make[1]: *** [scripts/mod] Error 2
make: *** [scripts] Error 2
I attach the kernel .config I used. I guess the assembler I built misses the support
for e200 core. How can enable it?

Yes, you'll need to create a device tree file for the board. Again, start from an existing 5200 .dts file. You won't need very much in it to get started.

I tried to create a first draft of the deveice tree for MPC5554. It is compilable with dtc. I based this .dts file on Figure 1-1 on page 1-3 and Table 1-2 on page 1-21 of http://www.freescale.com/files/32bit/doc/ref_manual/MPC5553_MPC5554_RM.pdf . I'm not sure about the following points: 1. Where should be the on-chip FLASH described? This memory is read-only from view of software and can be used to store read-only data or execute code directly from there. 2. Should the co-processor (eTPU in this case) also listed in section "cpus" or not? This co-processor is not able to run code like the e200z6. 3. There are three on-chip buses on MPC5554: - Crossbar Switch (XBAR) - Peripheral Bridge A (PBRIDGE_A) - Peripheral Bridge B (PBRIDGE_B) I used PBRIDGE_A and PRIDGE_B to create two /soc<SOCname> entries. Is this possible? 4. There are modules which have multiple instances at different base addresses. These are DSPI, SCI and FlexCAN. I used the same name for them but with different addresses.

Is= this possible? the soc5200 naming was poorly chosen when the 5200 device tree was written. Use something like this: xbar@<control-regs-base-address> { compatible =3D "fsl,mpc5554-xbar"; #address-cells =3D <1>; #size-cells =3D <1>; ranges =3D <[put the translation ranges in here]>; reg =3D <address and size of xbar control registers>; bridge@<bridgea-base-address> { compatible =3D "fsl,mpc5554-pbridge-a"; #address-cells =3D <1>; #size-cells =3D <1>; ranges =3D <[put the translation ranges in here]>; reg =3D <address and size of bridge control registers>; [... child device nodes ...] }; bridge@<bridgea-base-address> { compatible =3D "fsl,mpc5554-pbridge-b"; #address-cells =3D <1>; #size-cells =3D <1>; ranges =3D <[put the translation ranges in here]>; reg =3D <address and size of bridge control registers>; [... child device nodes ...] }; }; The idea is to use generic names for the node names, and identify exactly what the device is by using the "compatible" property. Also, the aim is to build up a tree describing the interconnection of device from the perspective of the OS on the CPU. ie. the full physical address space is represented by the root node of the tree, and everything else hangs off that. > 4.

I'm not quite sure whether the memory@40000000 should go under xbar or stay directly under the root node. The second problem I faced with was that XBAR covers the whole address range. However, if I specify "ranges = <0 0x00000000 0x100000000>;" then I get an error message because of the too big length value: | DTC: dts->dts on file "/usr/src/linux/arch/powerpc/boot/dts/mpc5554.dts" | /usr/src/linux/arch/powerpc/boot/dts/mpc5554.dts:51 literal out of range | FATAL ERROR: Syntax error parsing input tree I tried to solve this problem by assuming that leaving out the "ranges = ..." means the whole range.

No ranges property indicates that addresses cannot be directly translated across the bridge, which is not, I think, what you intend. > + reg = <0xfff04000 0x4000>; The unit address '@1ff04000' does not match your reg property 0xfff04000. > + > + flash@00000000 { // read-only FLASH Unit addresses are not 0 padded, so this should be just 'flash@0'. > + compatible = "fsl,mpc5554-flash"; > + reg = <0x00000000 0x200000>; // 2MiB internal FLASH > + }; > + > + bridge@c0000000 { > + compatible = "fsl,mpc5554-pbridge-a"; > + #address-cells = <1>; > + #size-cells = <1>; > + ranges = <0 0xc0000000 0x20000000>; > + reg = <0xc3f00000 0x4000>; The unit address is based on 'reg' (if present) not ranges, so it should be bridge@c3f00000. Likewise for the other bridge below. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.

You need to decide how each device is going to specify it's interrupt line. Often the first cell is the hardware interrupt number, and the second cell encodes the sense (high, low, edge). Conversely, PCI interrupts only use #interrupt-cells =3D <1> because all PCI irqs use the active low sense. Then, each device in the tree should have an 'interrupts =3D < [hwirq#] [sense]>;' property. Otherwise, starting to look pretty good. g. ^ permalink raw reply [flat|nested] 25+ messages in thread

Well, you could add those too, but "PowerPC,5554" should probably remain. The historical background here is that in the original OF spec, driver matching was done on node name, and only then on compatible. Essentially the node name was treated as an implicit first entry in the compatible list. The the generic names convention came along, and instead name became a human readable generic type for the device ("ethernet", "i2c", etc..). That convention has been widely used since long before flat trees existed, but for some reason it was never really used for cpu nodes; they remained as "PowerPC,XXXX" or whatever. Because the varying names of cpu nodes was sometimes awkward to deal with in bootloaders, we decided it would be sensible to apply the generic names convention here too, so "cpu@X". But then, the previous node name, which was treated as being prepended to compatible, should now explicitly be put into compatible. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.

In this particular case, we're talking about a part that has never previously been described in a device tree. So, since this is something entirely new, what is the value in preserving the PowerPC,XXXX style when there isn't any code that will be relying on it? g. --=20 Grant Likely, B.Sc., P.Eng.

There could be code that matches anything starting with "PowerPC,". Also, consistency is a good thing no matter what. Segher ^ permalink raw reply [flat|nested] 25+ messages in thread

Even with the generic names recommended practice, matching is _still_ done on "name" first, and only then "compatible". It isn't expected that anything will try to match one the generic names, so for "new style" nodes that in effect means matching on "compatible" only, but it is important for compatibility. > That convention has been widely used since long before flat trees > existed, but for some reason it was never really used for cpu nodes; > they remained as "PowerPC,XXXX" or whatever.

I need some more time to work on the others. In the meantime I send the intermediate version.

Yes, it is the small one (actually 64KiB, I corrected the comment also). I added the external memory of the MPC5554DEMO evaluation board which has a size of 512KiB. Would it be possible to program the uncompressed kernel to the FLASH so it can run directly from there? I guess for the code and the constant sections the FLASH could be a good place. Then cstart has to initialize the initialized variables by copying data from FLASH to RAM and fill the BSS area with zero.

I would keep the list like this because in this case it is easy to find which comment belongs to which interrupt number. Otherwise one would need to count the interrupt numbers and the comment to find out which number match which comment. >> + etpu@3fc0000 { // Enhanced Time Processing Unit >> + compatible = "fsl,mpc5554-etpu"; >> + reg = <0x03fc0000 0x4000>; >> + interrupts = <67 1 // Global Exception >> + 68 1 // A Channel 0 >> + 69 1 // A Channel 1 >> + 70 1 // A Channel 2 >> + 71 1 // A Channel 3 >> + 72 1 // A Channel 4 >> + 73 1 // A Channel 5 >> + 74 1 // A Channel 6 >> + 75 1 // A Channel 7 >> + 76 1 // A Channel 8 >> + 77 1 // A Channel 9 >> + 78 1 // A Channel 10 >> + 79 1 // A Channel 11 >> + 80 1 // A Channel 12 >> + 81 1 // A Channel 13 >> + 82 1 // A Channel 14 >> + 83 1 // A Channel 15 >> + 84 1 // A Channel 16 >> + 85 1 // A Channel 17 >> + 86 1 // A Channel 18 >> + 87 1 // A Channel 19 >> + 88 1 // A Channel 20 >> + 89 1 // A Channel 21 >> + 90 1 // A Channel 22 >> + 91 1 // A Channel 23 >> + 92 1 // A Channel 24 >> + 93 1 // A Channel 25 >> + 94 1 // A Channel 26 >> + 95 1 // A Channel 27 >> + 96 1 // A Channel 28 >> + 97 1 // A Channel 29 >> + 98 1 // A Channel 30 >> + 99 1 // A Channel 31 >> + 243 1 // B Channel 0 >> + 244 1 // B Channel 1 >> + 245 1 // B Channel 2 >> + 246 1 // B Channel 3 >> + 247 1 // B Channel 4 >> + 248 1 // B Channel 5 >> + 249 1 // B Channel 6 >> + 250 1 // B Channel 7 >> + 251 1 // B Channel 8 >> + 252 1 // B Channel 9 >> + 253 1 // B Channel 10 >> + 254 1 // B Channel 11 >> + 255 1 // B Channel 12 >> + 256 1 // B Channel 13 >> + 257 1 // B Channel 14 >> + 258 1 // B Channel 15 >> + 259 1 // B Channel 16 >> + 260 1 // B Channel 17 >> + 261 1 // B Channel 18 >> + 262 1 // B Channel 19 >> + 263 1 // B Channel 20 >> + 264 1 // B Channel 21 >> + 265 1 // B Channel 22 >> + 266 1 // B Channel 23 >> + 267 1 // B Channel 24 >> + 268 1 // B Channel 25 >> + 269 1 // B Channel 26 >> + 270 1 // B Channel 27 >> + 271 1 // B Channel 28 >> + 272 1 // B Channel 29 >> + 273 1 // B Channel 30 >> + 274 1>; // B Channel 31 > > Are A and B two instances of the same hardware block?

With this version of MPC5554 device tree I try to improve the eTPU related node. The Table 18-6 on page 18-15 in the http://www.freescale.com/files/32bit/doc/ref_manual/MPC5553_MPC5554_RM.pdf shows the detailed memory map of the eTPU. What is visible is that the eTPU A and eTPU B is interleaved in the memory map. For example ETPU_ECR_A is at Base + 0x0_0014 while ETPU_ECR_B is at Base + 0x0_0018. Then comes a register set for time base configuration: ETPU_TBCR_A is at Base + 0x0_0020, and ETPU_TBCR_B is at Base + 0x0_0040. As you can see the eTPU A and eTPU B registers are not just shifted by a fixed offset but comes interleaved according to the hardware designer wish. How can the multiple register ranges be expressed in device tree? Regards, Márton Németh --- From: Márton Németh <nm127@freemail.hu> Add device tree for Freescale MPC5554.

I'm a bit new on the topic, could you please describe what FSL means?

Hrm. It works, but not like one would expect, i.e. check out the help: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=search_help Last I checked the gitweb code, there was no easy way other than what you did by manipulating the URL directly.
